I'm new to X Window programming ... I typed in the example program
"helloworld.c" from Oliver Jones' book, "Introduction to the X Window
system", compiled, linked with the libs on a Sun, and ran it using
a remote server for the display (eXodus on a Mac, not that it should
matter). It does what it is supposed to do, except that when I tell it
to quit by hitting 'q', it crashes instead of terminating cleanly.
The error message is:
[2] Bus error      xhello core dumped

(I called it xhello).
All it does when it gets a 'q' that is different from any other 
keypress (which it correctly ignores) is to call XFreeGC,
XDestroyWindow, XCloseDisplay and exit. Does anyone have any
idea why it should crash??
