It seems that you have the definition of FDICreate incorrectly specified. I
don't have the C code header for that so can you post it on the list.

I suspect this because when you trace through the code, you can see the
callback function for allocate and free being called, but the parameter's
being passed to those functions are obviously wrong. The first allocate
callback is passed 2052, which seems ok. However the next call is passed the
PFNOPEN value! On my system that means it is being asked to allocate 4530592
bytes. Then the first myfree callback is being asked to free the PFNWRITE
address. Next the ReadFile callback is being asked to use the PFNSEEK value
as the file handle and to read the ERF value number of bytes. In my system
that means 4559848 bytes!

So I suspect that you may have missed a parameter?
