As part of an application we're developing, we use CreateFileMapping/MapViewOfFile to be able to share information among processes. I noticed today that if I try to reference the map immediately after calling fork() but before calling exec, that my application will crash.
I should be able to resolve this in my app but I was just curious if this was unexpected behavior or not.
