Any idea of how to track this back through cygwin1.dll > and into my app? Thanks. First you need to compile your application with debugging symbols (the '-g' flag to gcc/c++). Once you've done that you can start your program under gdb like so $ gdb /path/to/app.exe (gdb) run [put any args here] and you can then issue the 'bt' command to gdb to get the backtrace, or if you suspect the problem is occurring inside the (Cygwin) DLL you can do (gdb) dll cygwin1 (gdb) thread 1 (gdb) bt this... I may have some of the above wrong (?).
