Hello, I just post my experience with fontconfig, in case it may be useful for other users hitting similar problems: I have mylibrary.so bundling a statically linked version (2.13.1) of fontconfig and a 3rdpartylib.so bundling an unknown version of fontconfig, probably with static linking as well. In my process, when I load both libraries, functionalities of 3rdpartylib.so starts to misbehave, like common data (probably the cache, but I wasn't able to identify the exact location of this cache) being shared is getting corrupted. Searches directed me to bug reports like[1], with comments pointing to a recent change[2] in the caching mechanism of fontconfig. I checked out latest fonconfig repository, updated the copy of fontconfig in my library and the problem in the 3rd party library disappeared. I will monitor the situation in the next days but this seems the right solution for me. I just have a question: is 2.13.1 really the last stable version of fontconfig or 2.13.92 which is present in the release directory[3]? Official website[4] is still pointing to the former.
