This cache has the new magic.  How odd.

000000c0  65 31 2f 61 64 6f 62 65  73 74 64 33 35 00 00 *03*
000000d0  *fc* *02* *fc* 1e 8e 00 00 9e  9e b1 53 23 00 00 00 ee

(That's 03 fc 02 fc, which is what 0xfc02fc03 looks like when you write it.)

Are you sure that's an old cache?  It looks like a new cache to me, so 
that perhaps you have mixed versions of fontconfig.  My fontconfig 
crashes when you give it this file, but it should: it has the new MAGIC 
and an old format.

There doesn't seem to be any other explanation aside from mixed 
versions.  fontconfig definitely bails on caches with wrong MAGIC now.
