I just tried that testcase with Cygwin 1.7 and it appears to work most of the time. Unfortunately I can still reproduce the problem once per about 30 forks. I'll look into fixing this for Cygwin 1.7. However, please note that there is no *really* foolproof method to fix this due to the way fork has to be implemented using Win32 calls. I can only make it much more unlikely than today. > I think it would tough to modify the shmget/shmat calls to mmap for my > application. If you need to share memory only with forked processes, it's a much simpler solution. > > I believe V 1.7 is a Beta release, Can I know when the Official release will be? It's all in the announcement I referred you to.
