            Bug ID: 91178
           Summary: GCC fails with internal compiler error.
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vsevolod.livinskij at frtk dot ru
  Target Milestone: ---

GCC fails with an internal compiler error. Sometimes the compilation takes
about 5 minutes before it fails. Everything works fine with -O2.

Reproducer:
int a;
extern int f[10][91125];
int b[50];
void c() {
  for (int d = 6; d <= a; d++)
    for (int e = 16; e <= 24; e++)
      b[e] -= f[d][d];
}

Error:
>$ gcc -c -O3 small.c
gcc: internal compiler error: Segmentation fault signal terminated program cc1

GCC version:
gcc version 10.0.0 (revision: 273474)
