Windows-native DLLs that make use of the Microsoft C runtime are not compatible with Cygwin. They will not work properly.

You're saying that on this same computer, running Win 2012, this sample code ran properly under a previous version of Cygwin? Which version was that? > I have downloaded the source also, I check some varibel there if you can help. Which source have you downloaded?

Your sample program is getting exceptions (i.e., is faulting) even before it fork()s the child process. The child is faulting the same way. This looks pretty much like your sample program was built with incorrect assumptions. You can try posting the compilation (and linking) command(s) that you used to build your btrsamp.exe program. Maybe there's something obvious there that somebody here can see. We can't help you debug your program though, and you can't mix Windows-native DLLs that use Microsoft C runtime with Cygwin code. ..mark -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
