Yes, I think leaving the current behaviour probably makes sense. I encountered that test failure too and mask that test on the basis that that those builtins aren't documented as being guaranteed to work https://gcc.gnu.org/onlinedocs/gcc/Return-Address.html (that page even notes that crashing is allowable behaviour).
