open $fh, ">", \*glob causes SEGV

The segmentation violation actually happens when the glob is stringified, and only if the $fh has been printed to.

This crashes as of perl5.10.0:

$ perl5.8.9 -le' open my $fh, ">", \*STDOUT; print $fh "hello"; print *STDOUT'
*main::STDOUT
$ perl5.13.4 -le' open my $fh, ">", \*STDOUT; print $fh "hello"; print *STDOUT'
Segmentation fault

I believe it was change 22315/4ce457a648 that caused this. A patch is forthcoming.
