ICE caused by SEGV during a koji build (https://koji.fedoraproject.org/koji/taskinfo?taskID=81524235) on ppc64le:

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla> for instructions.

Version-Release number of selected component (if applicable):

12.0.1-0.2.fc36

How reproducible:

Two attempts in koji have failed the same way but I have been unable to reproduce it using the ppc64le test machine with the same compiler.

Additional info:

Although I couldn't reproduce it on the test machine running under valgrind did report a number of issues.

I will attach the preprocessed source and the valgrind log.
