I've become entirely desensitized to seawasp failing, which is probably
a bad thing, but today I happened to look at it and discovered that
its compiler has been dumping core for some time now:

clang: /home/fabien/llvm-src/llvm/lib/Transforms/Scalar/SROA.cpp:1745: llv=
m::Value* getAdjustedPtr({anonymous}::IRBuilderTy&, const llvm::DataLayout=
&, llvm::Value*, llvm::APInt, llvm::Type*, const llvm::Twine&): Assertion =
`Ptr->getType()->isOpaquePointerTy() && "Only opaque pointers supported"' =
failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/=
 and include the crash backtrace, preprocessed source, and associated run =
script.
Stack dump:
0.	Program arguments: /home/fabien/clgtk/bin/clang -Wno-ignored-attributes=
 -fno-strict-aliasing -fwrapv -fexcess-precision=3Dstandard -Xclang -no-op=
aque-pointers -Wno-unused-command-line-argument -Wno-compound-token-split-=

o=3Dthin -emit-llvm -c -o strftime.bc strftime.c
1.	<eof> parser at end of file
2.	Optimizer

Seems like we ought to look into that, and report it as requested.
