Page faults

Having just added more memory to prevent the disk swapping I was 
encountering, I now seem to be crashing with a page fault. I don't 
really know enough about how the memory is handled. Is this likely to be 
a wine bug?

I am running native versions of msvcrt and mfc42, but pretty much 
builtin for everything else. This is running Xilinx fpga_editor. When 
running on this particular design, it appears to use about 350MB of RAM.

Unhandled exception: page fault on write access to 0x9c5a7c4c in 32-bit 
code (0x7800d77a).
