--- Comment #13 from Jeffrey Walton <noloader at gmail dot com> --- The issue is cleared in GCC 9 from DEC 08 2018. Our self tests pass where they formerly failed. The failures are the reason I wanted a diagnostic run with UBsan. On GCC110 and GCC112 with gcc-9 located at /home/mik/misc/gcc-9, I was able to confirm there are no UBsan findings. I was not able to confirm the fix on GCC135, which is the original problematic machine. I did not find an updated gcc-8 or gcc-9 on GCC135. Thanks for the help.
