--- Comment #7 from G. Steinmetz <gscfq@t-online.de> ---
It gives an ICE for some target processors like -mtune=skylake,
but not for others like -mtune=sandybridge :


$ gcc-13-20230212 -c 20161124-1.c -O2 -mtune=skylake -fsanitize=undefined
-fvar-tracking-assignments -fselective-scheduling2
cc1: warning: var-tracking-assignments changes selective scheduling
during RTL pass: sched2
20161124-1.c: In function 'foo':
20161124-1.c:22:1: internal compiler error: Segmentation fault
