Subject: Must not insert cache into hash table before completely validating.
X-Git-Tag: 2.4.91~23
X-Git-Url: https://git.wh0rd.org/?p=fontconfig.git;a=commitdiff_plain;h=bc5e8adb4d05d1d03007951f46aaacc63c3b2197

Must not insert cache into hash table before completely validating.

The cache was inserted into the hash table before the timestamps in the
cache were verified; if that verification failed, an extra pointer to the
now freed cache would be left in the hash table. FcFini would fail an
assertion as a result.
