Do you know which version of Xserver that worked you updated from?

Examining /var/log/setup.log and/or using setup to revert to the previous
version should tell you.

I'm afraid I'm not able to reproduce this (testing using an xfs running on
Solaris, I don't have access to AIX).

Can you please obtain a backtrace as follows:
1) Install gdb (for gdb) and sysvinit (for pidof) packages
2) Start XWin using your normal method
3) In a non-X terminal window, run gdb --pid=`pidof /usr/bin/XWin`
4) Type 'c' at the '(gdb)' prompt
5) Reproduce your crash
6) Type 'bt full' at the '(gdb)' prompt.
