Regardless of any possible fault in git-svn, there's an obvious bug here
with git-fsck. Can you share the pack (if the project is public) or
compile a git-fsck without optimization and with debugging, and run it
under valgrind, to hopefully get us a backtrace of where the memory
management goes off the rails?
Unfortunately I'm unable to share the pack.
As Java Developer I'm note very savy, but I'd try.
Do you have me any pointers on ".. without optimization and with
debugging" and "run it under valgrind"?
Currently I used
deb http://ppa.launchpad.net/git-core/ppa/ubuntu quantal main
as source.
