FYI, I get an almost identical problem on a very up-to-date Gentoo  
Linux system, except the pty ID is different, and it actually exists,  
but its default permissions do not allow whatever the debugger is  
trying to do:

	(gdb) run input.txt
	/dev/ptyz0: Permission denied.

	Program exited with code 01.
	You can't do that without a process to debug.

My /dev/ptyz0 is a symbolic link to /dev/pty/m160, permissions  
crw-------.

I suspect I can change the permissions to get around the problem, but I  
don't know what the implications of the permissions on these devices  
are.


Also, in case it's relevant, I'm using the new 'udev' device managment  
system:

	root> ps x
	...
	2256 ?        S<s    0:00 udevd
	2449 ?        Ss     0:00 /sbin/devfsd /dev
	...

Maybe this second view will help triangulate on the problem...
