Hi The gdb tty option and command is broken on cygwin. After setting a tty for the inferior, the first run seems OK, but the second sometimes fails and the third may cause gdb to hang or enter an infinite loop. The fix is to close the (redundant) tty fd *before* launching the inferior process instead of after. This fix is necessary to support anjuta and other gdb interfaces on cygwin.
Changelog entry: 2002-12-31 Steven O'Brien <[EMAIL PROTECTED]> * gdb/win32-nat.c (child_create_inferior): close tty fd before launching the inferior process.
