| Subject: | segfault with Return::Value1 1.26 and perl 5.6.1 |
This only happens with "failure" objects; "success" objects are fine, as
far as I can tell.
# perl -MReturn::Value -le 'my $r = failure; if (!$r) { print "do not segfault" }; if ($r) { print "segfault" }'
do not segfault
zsh: segmentation fault perl -MReturn::Value -le
# perl -MReturn::Value -le 'my $r = failure; if (!$r) { print "do not segfault" }; if (!!$r) { print "segfault" }'
do not segfault
# perl -MReturn::Value -le 'my $r = failure; if (!$r) { print "do not segfault" }; if ($r + 0) { print "segfault" }'
do not segfault
# perl -MReturn::Value -le 'my $r = failure; if (!$r) { print "do not segfault" }; if ($r > 0) { print "segfault" }'
do not segfault
# perl -V
