Subject: [PATCH] Fix assertion in FcFini()
|
|
|
|
Due to the unproper initialization of `latest_mtime', the duplicate caches
|
|
was still in fcCacheChains with no references. which means no one frees
|
|
them. thus, the memory leak was happened.
|
|
|
|
Fixes https://gitlab.freedesktop.org/fontconfig/fontconfig/issues/227
