           Summary: [7/8/9 Regression] ICE in build_call_expr_loc_array at
                    gcc/tree.c:11563 since r229082
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

Following is causing ICE:

$ cat atomic.c
_Atomic double a;
int b;

void c() { a += b; }

$ gcc -mfpmath=sse,387 -msoft-float -mno-sse -c atomic.c
atomic.c: In function ‘c’:
atomic.c:4:1: internal compiler error: Segmentation fault
    4 | void c() { a += b; }
