Hi Paul,
This bot has built the tblgen binary with sanitizers and what you're
seeing is an undefined behaviour issue at runtime. The lines are
showing the callstack for it (in between the filecheck annotations).
So presumably if you look at:
10: SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior
/b/sanitizer-x86_64-linux-fast/build/llvm-project/llvm/lib/TableGen/TGParser.cpp:3213:22
in
That file/line would give you an idea of the problem, a null pointer
use I assume.
If you run the RUN line in a terminal, without the pipe into
FileCheck, you will get a better view of the output.
