Thomas pointed out to me that thorntail also failed, and that it
included a backtrace. Unfortunately it's not somewhat confusing. The
innermost frame is:
#0 0x00000100006319a4 in bbsink_archive_contents (len=<optimized
out>, sink=<optimized out>) at
/home/nm/farm/sparc64_deb10_gcc_64_ubsan/HEAD/pgsql.build/../pgsql/src/backend/replication/basebackup.c:1672
1672 return true;
Line 1672 of basebackup.c is indeed "return true" but we're inside of
sendFile(), not bbsink_archive_contents(). However,
bbsink_archive_contents() is an inline function so maybe the failure
is misattributed. I wonder whether the "sink" pointer in that function
is somehow not valid ... but I don't know how that would happen, or
why it would happen only on this machine.
