Re: Reproducible, corrupt packfile after fresh git-svn checkout

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.

Try something like

  # The package names might be wrong and/or you may need additional -dev
  # packages, I don't know the specifics for ubuntu
  apt-get install gcc make valgrind libcurl-dev zlib-dev
  cd
  git clone git://git.kernel.org/pub/scm/git/git.git
  cd git
  echo 'CFLAGS = -O0 -g' >>config.mak
  make
  cd /path/to/repo
  valgrind --track-origins=yes ~/git/git-fsck

It'll be very slow, at least 20x the normal runtime, so don't be
surprised if it doesn't seem to get anywhere at first.
