Subject: [PATCH v2 1/2] cherry-pick: demonstrate a segmentation fault
Date: Sat, 26 Nov 2016 13:48:02 +0100 (CET) [thread overview]
Message-ID: <f1a1fbf148e1f0106f47ea0153c4eb0dfa3bd21b.1480164459.git.johannes.schindelin@gmx.de> (raw)
In-Reply-To: <cover.1480164459.git.johannes.schindelin@gmx.de>
In https://github.com/git-for-windows/git/issues/952, a complicated
scenario was described that leads to a segmentation fault in
cherry-pick.
It boils down to a certain code path involving a renamed file that is
dirty, for which `refresh_cache_entry()` returns `NULL`, and that
`NULL` not being handled properly.
