Fixed in perl-Switch-2.17-1.fc21. A change in perl-Filter-1.50 caused the FTBFS.

I upgraded the perl-Filter to 1.50 in all Fedoras because the reblessing was a bug. I think the Switch-2.17-Filter-1.50.patch should be applied in F20 and 19 too <https://bugzilla.redhat.com/show_bug.cgi?id=1105167#c6>.

BTW, I cannot see the patch in the upstream bug tracker <https://rt.cpan.org/Public/Dist/Display.html?Name=Switch>. Is something wrong with the patch?

I have the problem on fc20
perl -d

forgot the version when the problem can be seen:
- perl-Filter-1.50-1.fc20.x86_64
- perl-Switch-2.16-8.fc20.noarch
- perl-5.18.2-289.fc20.x86_64

Nah, I think the patch is fine, I just forgot to submit it upstream. I've just done that:

https://rt.cpan.org/Public/Bug/Display.html?id=96736

I'll go ahead and build for f19/f20.

I think this is a different bug in perl debugger or perl filters independent of Switch version. This kind of warning has been introduced in Perl 5.16. Please report a new bug report. However I worry this a principal limitation of perl debugger. Asking perl developers (using perlbug tool or <https://rt.perl.org/Public/>) would be the best approach in this case.

I was hit by this bug in F20 x86_64:

$ rpm -q perl-Switch perl-Filter
perl-Switch-2.16-8.fc20.noarch
perl-Filter-1.50-1.fc20.x86_64

$ perl -e 'use Switch;'
Can't call method "filter" on unblessed reference at -e line 2.
$

I applied the perl-Switch-2.17-1.fc20 update from updates-testing and am happy to report that it solved my issue.

Can someone put this in overrides / push it to stable?
