--- Comment #3 from Sergei Trofimovich ---
Posting example from PR107789 here in unlikely case it's a slightly different
problem:
$ cat a.c.c
long ga, gb, gc, gd;
unsigned long ge, gf;
int gh;
int bug(void) {
gf = gb ? ga : 0;
gf -= gh * ge;
gc += gd * ge;
if (gf)
gc += gf;
return 0;
}
Crashes as:
$ gcc -std=c99 -O2 -c a.c.c -o a.o -O2
during GIMPLE pass: slp
a.c.c: In function 'bug':
a.c.c:4:5: internal compiler error: Segmentation fault
