SVK produces "Attempt to free unreferenced scalar" errors as described in #455410. The underlying cause is a bug in PerlIO::via included in the core Perl 5.10.0 as described in the Perl bug #54934 (http://rt.perl.org/rt3/Public/Bug/Display.html?id=54934). That bug includes a patch which fixes the problem and will presumably be included in Perl 5.10.1. Can that patch be applied to the Perl 5.10.0 in Fedora 10 and Rawhide?
Will be this fix also needed for F-9? The blocking bug #455410 was reported against F-9.
It will be needed for F-9. Perl 5.10.0 has the bug.
