I'm not sure what you mean, fsclose doesn't deal with filenames?

No, the filenames below look OK to me and are similar to what I have.
If fsopen returns a valid fd (i.e., not -1), then you know it opened
the file successfully.

Is it still crashing in fc_Patternreference? I would check the incoming
arguments to make sure they're valid and if not trace back the call
chain to see what provided the invalid argument.

I assume you're using shared libraries? You can use *SOMAddress to find
the offset in the fontconfig library of the crash and then load it into
!Zap to look at the disassembler and find the rogue instruction. Cross
reference that with registers from *showregs and you should see a reason
for the crash. It may be something obvious like a NULL value on entry.
