- Subject: [PATCH] fix broken tty command on cygwin
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 <steven.obrien2@ntlworld.com>
* gdb/win32-nat.c (child_create_inferior): close tty fd before
launching the inferior process.
