Re: git svn fetch segfault on exit
I'm facing the same issue. I'm using git-1.8.4 and subversion 1.8.3 on Ubuntu. I'm proposing a different modification to Ra.pm: Jonathan's modifications basically disable the use of $RA. The modifications above ensure that the destructor of $RA is called before doing an apr_terminate().

Can you check if your version of the perl subversion bindings were
compiled against the perl and subversion versions that you have
installed?
Perl -- as an interpreted language -- is mostly supposed to be safe from
such segfaults, and since git-svn is pure perl, the likely culprit is in
the bindings or the svn libraries. And the easiest way to get that to
break is a version mismatch.

git svn fetch segfault on exit
Hi,
I'm using archlinux with git version 1.8.3.3, svn version 1.8.0
(r1490375) and perl v5.18.0 (built for x86_64-linux-thread-multi)
Every git svn call that involves a fetch produces a segmentation fault
on exit (but the operation succeeds).

This bug has already been reported by others on subversion mailing list
and and archlinux bbs:
https://bugs.archlinux.org/task/36070
http://permalink.gmane.org/gmane.comp.version-control.subversion.user/114019
I tried to fix it but the problem is that I know absolutely nothing of
perl. Anyway, I noticed that with the modifications bellow (in
Git::SVN::Ra::new) the crash does not occur (I do not think it's a real
fix though).
