You really should try B20 if you want the absolute best cygwin out there. >2.

No inspection of the man page was needed to determine that there was an obvious problem with your example. Hmm. Now that I look at it again, I will admit that I was wrong in my analysis. Your code snippet wouldn't have compiled. I should have assumed that you were missing an opening parentheses in the below. If your further bug report is true, this wouldn't have done me any good but it does mean that I had wrongly interpreted your code to assume that rslt would be set to a boolean value rather than the output of mmap. You had: if (rslt = mmap(0, size, prot, MAP_SHARED, fd, offset)) == MAP_FAILED) I misread it as: if (rslt = mmap(0, size, prot, MAP_SHARED, fd, offset) == MAP_FAILED) It should be: if ((rslt = mmap(0, size, prot, MAP_SHARED, fd, offset)) == MAP_FAILED) >The seg fault only occurs in version 1.3.20.

Although you've taken great offense at the suggestion that a real test case was required, you seem to have provided something that we can now use to fix cygwin. Thank you for the test case and analysis. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
