Description Vsevolod Livinskii 2021-11-07 19:26:24 UTC
The bug is not reproducible on the trunk anymore (the reduction process took forever).
I don't know if it was fixed or became latent. Feel free to close it if it is not relevant anymore.

Reproducer:
unsigned short a;
bool b;
int h, f;
extern bool d[][1];
char g;
void i() {
  for (short c = 0; c < 10; c += 3)
    for (unsigned e = 0; e < a; e = (d[c][0] ? true : 5) * (6021496ULL * b) ?: f)
      h = g;
}

Error:
>$ g++ -O2 -c func.cpp
during GIMPLE pass: vrp
func.cpp: In function 'void i()':
