---------------------------------------------------------------------- 
This issue can be fixed by disabling the frame cache in frame.c by defining
LOW_MEMORY near the top of the file. I can't see anything specifically
wrong in the frame cache code and it doesn't crash with anything else but
fax reception.

What appears to happen is an invalid frame is freed from the cache
(causing a crash) which as far as I can tell from traces I put in the code
never entered the cache.
