Description
Some of the built-in functions in builtin:: crash when called via goto &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 fault
Expected behavior
No crash.
