[bug] git-svn segmentation fault

[bug] git-svn segmentation fault

[Kosenko Roman]

Hello,
I use git-svn. I have used it without any problem for two month. Now
git starts crashing after "svn rebase" (maybe also after other
operations with a remote svn server, I'll check when will do "svn
dcommit" next time). It successfully done the operation and only then
it crashes:

$ git svn rebase
Current branch master is up to date.
error: git-svn died of signal 11

$ dmesg | tail -n5

This behaviour is persistent and I can reproduce it any time.

I don't know exact version of Subversion on the remote server (web ui
doesn't show it).
Core dump: http://madkite.cc/git/core.git-svn.1000.e28aeb54778749879c9313b05ea040e8.26467.1439282047000000.lz4

I have tried on another environment (cygwin x64, git 2.4.5, svn
1.8.13, perl 5.14.4) - it works fine with the same repo.
Also my environment works fine with other repos.

Is there anything else you need from me?

Best regards, Roman.

Sorry for bothering, it seems like this is not related to git, this is
because of broken subversion package in this buggy archlinux.
