Description
Some of the built-in functions inbuiltin:: crash when called viagoto &builtin::X.
This is (one of) the underlying issue(s) from#22528. I'm reporting it separately so it doesn't get lost even if Tie::RefHash::Weak gets fixed (or rather, a workaround is deployed in Tie::RefHash). As noted in#22528 (comment) by@leonerd:
Huh. Exciting times:
$ bleadperl -E 'sub { goto &builtin::refaddr }->(0)'panic: pad_sv po at -e line 1.
Steps to Reproduce
$ ./perl -e 'sub { goto &builtin::refaddr }->([])'Segmentation fault$ ./perl -e 'sub { goto &builtin::reftype }->([])'Segmentation fault$ ./perl -e 'sub { goto &builtin::stringify }->([])'Segmentation fault$ ./perl -e 'sub { goto &builtin::trim }->([])'Segmentation faultExpected behavior
No crash.
