The most common way is to put a breakpoint in the code before you get the stack corruption and step along until you see the problem. This isn't really Cygwin-specific advise though. You may want to read up on some of the capabilities of 'gdb' to gain more insights into it's capabilities. That should help you understand the things it can do to help you find problems. -- Larry Hall http://www.rfk.com RFK Partners, Inc. (508) 893-9779 - RFK Office 216 Dalton Rd.
