Interesting.  Could you run mgetty from inside gdb and send me a stack
trace when this happens?  ("gdb mgetty -> run -x9 tty1 -> where")

Yes, this is normal - mgetty must be run from inittab.

So something crashes here...  interesting indeed.  I will try to reproduce
that on AIX 4.3 next week, but for all our customer's machines on 4.3, it
works nicely so far.

How does the log look like with "-x9"?
