* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15 Henson Choi <[email protected]>

From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)
The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15 Henson Choi <[email protected]>
0 siblings, 0 replies; 114+ messages in thread
From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)
The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15 Henson Choi <[email protected]>
0 siblings, 0 replies; 114+ messages in thread
From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)
The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15 Henson Choi <[email protected]>

From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)
The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15 Henson Choi <[email protected]>
0 siblings, 0 replies; 114+ messages in thread
From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)
The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15 Henson Choi <[email protected]>
0 siblings, 0 replies; 114+ messages in thread
From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)
The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15 Henson Choi <[email protected]>

From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)
The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.

* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15 Henson Choi <[email protected]>

From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)
The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode. Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL. The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.
Filter sanitizer flags out of c_args during bitcode generation.
