Subject: valgrind: Add suppression for dbm_open(3)'s write(2).
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/d07c6759a3b5b936e790834147ab7bd867645d4f

valgrind: Add suppression for dbm_open(3)'s write(2).

It writes bytes from an area it mallocs, but doesn't set all of those
bytes first.  See with gdbm 1.13-1 on Arch Linux.
