Package: perl-base
Version: 5.8.0-10
Try this (note the shell redirection "1>&-" to close stdout):
$ perl -e 'open(FOO, ">&STDOUT") or die "open: $!"' 1>&-
Segmentation fault
FYI: perl 5.6.0 produces:
open: Bad file number at -e line 1.
Cheers, Roderich

And also in 5.10.0-19lenny3, but not 5.10.1-17. Nothing on the upstream
bug report. Couldn't find an obvious source change to explain it, but
