To fetch sources and compile:

  git clone https://github.com/git/git.git
  cd git/
  make CFLAGS='-g -O0'

To run gdb:

  gdb --args ./git fsck

Then type "run" at the gdb prompt. When the program crashes, you should
get the gdb prompt back. Then, typing "bt" gives you a backtrace, and
"bt full" gives you the same with more information (be careful, there
may be private information in it).

To use valgrind, just do:

  valgrind ./git fsck

(essentially, it runs the program adding a bunch of runtime checks hence
may provide better diagnosis)
