(i.e. run the executable under gdb and fetch stack trace from it). Thanks for the stacktrace! Looks like I've fixed the problem in LLVM r237045: due to a bug, UBSan initialization was *not* called from .preinit_array as it was supposed to, and if the function called from .init_array early enough contained an error and tried to report it (as in your case), the runtime was still in uninitialized state. Could you please test your code with trunk Clang?
It's fixed. Thanks for the prompt attention, and apologies for my tardy response.
