Multiple clang passes encountering 'pass error'

[gargaroff]

I was reducing a pre-processed test case with 8 jobs in parallel and 11 passes encountered a pass error. I have attached a zip archive with the created bug report for each of them.

If you need any other info, let me know.

Thank you very much for the report. However, I was unable to reproduce the failures with both LLVM9 and LLVM10. What version of libllvm do you use? Try ldd ./clang_delta/clang_delta.

Can you please try to run:

$ ./clang_delta/clang_delta --transformation=aggregate-to-scalar /tmp/cvise_bug_0/t15_20acase1.i --counter=1

You can also try to run it in a gdb.

I'm using LLVM11, built from source (Debug+Asserts and Release+Asserts), commit hash llvm/llvm-project@052c962ced7, should have mentioned that in the beginning.

I cannot run the above command at this moment, so hopefully knowing that LLVM11 was used enough for you at this point. If you still need the command output at a later stage, I'll do it once I get the time.

Thanks!
That explains why I can't reproduce that. Please use a released LLVM version, note that LLVM11 is a development branch and I would expect some failures..
