There are three instances of ‘SvTYPE(mysv) == SVt_PVGV’ in vms/vms.c, one in candelete_fromperl and two in rmscopy_from_perl. I think they should actually be isGV_with_GP(mysv).

Without that change, a glob in a PVLV will not be recognised as a glob. Currently, a PVLV will never hold a glob, though that was supposed to be possible as of 5.9.1. Half the perl source code was modified to support them. See bug #77362.

Once the patch for #77632 is applied, it should be possible to write failing tests for this.

To test these you can put a glob in a PVLV by passing a nonexistent hash element to a subroutine and then assigning a glob to it:

  my %hash;
  sub { for(shift) {
   $_ = *foo;
   # ... test candelete and rmscopy with $_ ...

Not having access to VMS, I am hesitant to write a patch myself, as I have no way of testing it.

This perlbug -d output is quite meaningless, as it’s not for the machine on which this bug will occur:
