Wine bug with MFC/C++?

It appears that Wine cannot use tmpfs... so far my testing only works using 
swap :o( which I do have enabled at home and it crashes. At work I have a 
500MB swap space and the same exact program does not crash there.

It's not convenient for me to run swap at home, so does anyone know a fix 
for this?

The code seems to require approx 500MB free memory. Since I only have 500MB 
RAM, I setup tmpfs on /tmp. But wine doesn't seem to use any of it.
