Over the past few weeks I had noticed that 'git svn rebase' had stopped working on one of my systems some time around the upgrading to Slackware-13.37. I was getting the error message:
Bizarre copy of UNKNOWN in subroutine entry at /usr/lib/perl5/vendor_perl/SVN/Base.pm line 80.
So this morning I finally did some digging on Google and found some discussion of this bug.
And a patch (which has fixed the issue for me).
I figured I'd share this here in case any other Slackware 32-bit users were also having trouble with it.
