[MPlayer-dev-eng] [PATCH] Fix fontconfig crash when it can't find a config directory

[Adrian Stutz]

Hello,

FcFontMatch in font_load_ft.c expects its third argument to be a pointer and
tries to assign it a result value when an error occurs. Current code passes
0 to the function, which leads to a crash if no font can be matched. This is
the case if no fontconfig config directory (and therefore no fonts) can be
found on the system.

This patch passes a proper pointer to the function, checks if it fails and
falls back to the non-fontconfig behavior in that case.

Greetings
Adrian
