xlock dies under A/UX

[Huw Davies - La Trobe University Computer Centre]

Has anyone had any sucess in getting the X11R4 application xlock running
under A/UX? I have got it to compile, and when it's run the screen saver
works fine. However, when a key is pressed to get the password window
up, xlock crashes with a segmentation fault.

Additional info:

xlock is a screen saver that secures your terminal - you have to enter
your password to continue.

A/UX v2.0
Same problem with both A/UX cc and gcc 1.38
