Bug#298551: xterm: fatal pty error 23 (errno=22) on tty /dev/pts/1

[Jochen Voss <voss@debian.org>]

Package: xterm
Version: 4.3.0.dfsg.1-12
Severity: normal

Hello,

on my shiny new Apple Powerbook G4 I encounter the problem described
in (closed) bug #105874.  The problem is the following:

When I try to start xterm with eightBitInput set to false, I opens a
window for a fraction of a second but then dies with the error message

    xterm: fatal pty error 23 (errno=22) on tty /dev/pts/1

The problem goes away when I set eightBitInput to true.  The problem
did not occur when a virtually identical configuration was used on an i386
based system.

My feeble debugging attempts could narrow down the source of the problem
a little bit: the error message is caused by the following lines of
code (xterm/main.c, lines 3547-3548):

		if (ioctl(ttyfd, TCSETA, &tio) == -1)
		    HsSysError(cp_pipe[1], ERROR_TIOCSETP);

This is executed in the child process after the fork, and the error
condition is reported back to the parent process via a pipe in an a
little bit convoluted manner.

Some information about my laptop can be found on my home page at
http://seehuhn.de/comp/powerbook/ .  If you need any further information
please ask.

I hope this helps,
Jochen
