           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal

Preprocessed source (-freport-bug)

The following code (reduced example) triggers an ICE with a recent `master`
(96e4244ef3ccf4867ca4e37fbc6800e64ef30af6).

$ cat test.ii 
extern "C" double sqrt(double);
double a, b, c;
void d() {
  for (;;) {
    c = __builtin_fabs(a);
    sqrt(c);
    if (a)
      a = b;
  }
}

$ /home/aland/gcc-trunk/bin/g++ -O2 -c test.ii
during GIMPLE pass: thread
test.ii: In function ‘void d()’:
