[PATCH 0/2] Fix crashes due to real_pathdup() potentially returning NULL




This problem was identified as the root cause for what seemed to be a
path conversion problem in the MSYS2 runtime at first glance.

Original bug report:
http://public-inbox.org/git/CAFKRc7y_kpCGNORENUZ2qw_4qBwjjyaaDFxAEQa52fTryj+w7A@xxxxxxxxxxxxxx/

We may want to consider fast-tracking this into v2.12.1, and to that
end, I would appreciate code reviews that focus on the correctness of
this patch and that try to consider undesired side effects.


Johannes Schindelin (2):
  Demonstrate NULL pointer access with invalid GIT_WORK_TREE
  Fix callsites of real_pathdup() that wanted it to die on error
