When debugging problems in cygwin, or even in programs like make, I've found it immensely useful to use Egor Duda's addition to Cygwin. If you set cygwin=error_start=x:\somewhere\gdb.exe, gdb will pop up whenever cygwin encounters a signal that will cause the program to terminate. For this to be effective with a buggy cygwin, y ou have to put the gdb in a separate directory with a cygwin that has been built with --enable-debugging so that there is no shared memory collisions. If you compile with --enable-debugging, there are additional consistency checks added to cygwin which will notify you when you attempt to close a handle that shouldn't be closed. gdb will also be started when cygwin prints a fatal message. FYI, cgf
