In various situations a cast that is ultimately unreahcable may produce an UNDEFINED result, and we can't check the bounds in this case. PR tree-optimization/120277 gcc/ * range-op-ptr.cc (operator_cast::fold_range): Check if the cast if UNDEFINED before setting bounds. gcc/testsuite/ * gcc.dg/pr120277.c: New.
