Has nothing to do with fontconfig, it's the libpostprocess it has trouble compiling.
"internal compiler error" means your compiler is buggy (or sometimes it can mean your computer's RAM is bad, mostly if it happens randomly) and doesn't manage to compile the file.
You'll have to use a different compiler.
Compiling for 64-bit might help as well.
As I don't think there is anything we can or should do about it, and unfortunately I don't see an easy workaround either I am closing this.
Feel free to reopen if there is any evidence that this is anything other than a compiler bug.
