Reduced testcase (-O2 to invoke the ICE):
void zgemm_ (const int*, const double*);
extern void matmul_c8 (_Complex double * dest)
{
const int ldc = 0;
const double zero = 0;
zgemm_ ( &zero, &ldc);
dest[1] += 1 ;
}
-----------------------------------------------------
Unlike PR26626, the code above is not questionable code if it is undefined or
not.
