I've also been working with another user off-list the past few
days on tracking down on a segmentation fault in git-svn.

I just ran this several (6?) times got a segmentation fault once
with Junio's master @ f948792990f82a35bf0c98510e7511ef8acb9cd3.

Trying it again with the same file that segfaulted earlier, it was
successful, spooky...

I also tried some other patches (see replies) which I've been testing to
fix the other user's problem.

I have definitely not seen this pattern before.

However, the following clone has been problematic at times

git svn clone svn://svn.debian.org/svn/pkg-glibc/glibc-package \
  -T trunk -b branches -t tags

I'm running x86, Debian Etch, SVN 1.4.2 from Debian Etch or
1.4.3 from Debian experimental + do_switch patch[1]

Thanks for the stack trace.  This is segfaulting at
a different place (expected, being an http:// repo while
the other is svn://)
