Usually the bots should not be the first line of defense, the unit tests in the repo should be. The bot might go away or some other changes in other parts of LLVM/Clang/Sanitizers may change and hide the failure.

If possible, please try to get a reduced IR test case for the failure. This will provide a more solid guard against the error in the future.

Cheers,
Florian
