--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Reduced testcase - albeit with different missing insn:
./gcc/cc1 -O2 reshape_generic-17.i
extern _Noreturn void runtime_error (const char *, ...) ;
void reshape_internal (long int rdim)
{
long int shape_data[15];
int seen[15];
for (int n = 0; n < rdim; n++)
if (shape_data[n])
runtime_error("%ld", (long int) n+1);
long int v = 0;
for (int n = 0; n < rdim; n++)
seen[n] = 0;
if (seen[v] != 0)
runtime_error("");
}
