           Summary: ICE during GIMPLE pass: slp in operator[], at
                    vec.h:867
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

>$ g++ -c -O3 func.cpp
during GIMPLE pass: slp
func.cpp: In function ‘void test(short int, bool, int)’:
func.cpp:3:6: internal compiler error: in operator[], at vec.h:867

Reproducer:
extern int arr_6[];
extern char arr_7[] __attribute__((aligned));
void test(short a, bool, int p8) {
  for (bool b = 0; b < (bool)p8; b = 1)
    for (short c = 0; c < 5; c++) {
      arr_6[c] = (long)2 << a - 30574;
      arr_7[c] = 0;
    }
}
