Coincidentally I was going to suggest something similar...
I got a hint lately about stuff working different on 64bit. If a 32 bit
application is called from a 64 bit application the stack is 0xc000
lower than if the same 32 bit application is called by another 32 bit
application. E. g., the first bash is spawned from 64 bit cmd.exe, its
stack is shifted 0xc000. A CreateProcess call from fork will now create
a child with the stack at another location which breaks the longjmp.
