git svn problems

andrnils

Hi,

I'm having some troubles with git on my FreeBSD 8.2 amd64 box. I'm using serf for http(s) access.

More specifically, using git's svn capabilities. On trying to clone a svn repo ( even an empty one ) I get:

Code: 
$ git svn clone [url]https://url/trunk/relng[/url]
Initialized empty Git repository in /tmp/relng/.git/
r1527 = 9bd86559f46df65ed71f4f0c7f13e110fcceec81 (refs/remotes/git-svn)
Checked out HEAD:
  [url]https://url/trunk/relng[/url] r1527
error: git-svn died of signal 11
andrnils@jailer:/tmp 11:14:22 139

The core file left reveals

Anyone seen something similar? I tried on a Linux system as well, and there it works.

Hmm, so it seems that git svn has caused problems before, with threading and perl's garbage collect.

I disabled threading in both perl and apr1 and rebuilt subversion, p5-subversion, serf and git ( not in that order ). Serf doesn't build without threads in apr ( serfs test-cases breaks, I disabled them in the Makefile ).

With this setup I also get a segfault, but somewhere else:

Still a bit confused about what's going on here.
 
And a backtrace with perl built with debuging symbols:
