Not sure if I qualify...but here goes:

I've been lucky enough to stay away from FileSystem.File till now, but I
have encountered a similar problem with pointers like the one you mentioned.
The bug is that for some reason, you are attempting to DEALLOCATE NIL!
During debuging stages, I add, IF Ptr#NIL THEN DEALLOCATE (Ptr,SIZE(Ptr))....
That should help a little.  If you don't know where its crashing, you can
use the dbgMap feature to locate the problem procedure.
