RolandF added a comment.

This revision causes a traceback when compiling SPEC2017 523.xalanbmk_r with -O3 -m64 -mcpu=power9 -flto and PGO, on the -fprofile-use compile step for XMLDateTime.cpp.  Can you please take a look?  Let me know if don't have access to SPEC0217 source and need a reproducer.  The traceback was as follows:
