Subject: name-hash.c: always initialize dir_next pointer
X-Git-Tag: v1.7.8-rc1~10^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=395c73560b3716a1f74124826b80ab7ec47d7cd8;p=thirdparty%2Fgit.git

name-hash.c: always initialize dir_next pointer

Test t2021-checkout-overwrite.sh reveals a segfault in 'git add' on a
case-insensitive file system when git is compiled with XMALLOC_POISON
defined. The reason is that 2548183b (fix phantom untracked files when
core.ignorecase is set) added a new member dir_next to struct cache_entry,
but forgot to initialize it in all cases.
