            Bug ID: 105132
           Summary: ICE in in operator[], at vec.h:889 with
                    -march=skylake-avx512 -O3
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vsevolod.livinskiy at gmail dot com
  Target Milestone: ---

Link to the Compiler Explorer: https://godbolt.org/z/xedcfP338

Reproducer:
short a;
extern int b[];
int c;
void d(long f[][5][5][17], int g[][5][5][17]) {
  for (short e = 0; e < 17; e++) {
    a = g[19][2][3][e];
    b[e] = c & (f[3][2][3][e] && g[19][2][3][e]);
  }
}

Error:
>$ g++ -march=skylake-avx512 -c -O3 func.cpp
during GIMPLE pass: slp
func.cpp: In function 'void d(long int (*)[5][5][17], int (*)[5][5][17])':
