--- Comment #3 from mcccs at gmx dot com --- Created attachment 61163 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=61163&action=edit cleaned up I cleaned up the testcase, without changing the arithmetic, so it passes with 14.2 -O3 and trunk -O0, while failing with trunk -Os. It turns out my cleanup revealed another latent bug - it now aborts with trunk -O3 as well
