No problem.

Your mail to the list from 3 days ago showed up in my mailbox AFTER this
one...looks like it got hung up on the AT&T listserver for some reason
according to the headers.

Well, I'll see what I can do but I can't make any promises... :)

Yeah, that site died a few weeks ago for some reason, still not sure why as I
haven't talked to the person who runs the site in a while, and I haven't had
time (or, honestly, much ambition) to set up a new one (although I did snag the
cached HTML from Google so I do have it to slap up on a new site when I get
around to setting one up). I would have set up a new one right away if I was
still working with the AIX platform, but since I'm not...sorry! :)

Hm.

It is the stock 3.3.3, if I remember correctly, so it's getting a little long
in the tooth now (and it was compiled against AIX 4.1.5, which is now quite
old as well and who knows what differences might be appearing in the shared
libs of the more recent AIX versions that could be causing problems).

The default depth is 8 with a TrueColor visual, if I remember correctly, and
the version should be 3.3.3 so the Q15 problem shouldn't be present in there.
Unfortunately I really have no ideas about why it's core dumping, sorry.
I do have a couple of suggestions though. Rebuild the latest version yourself
(it's not that difficult and I've included the patch below since the web site
with it is gone, or you could grab someone else's more recent precompiled
version, there are a couple of others mentioned in the archives if you search
back, or Tridia has an AIX version you can download of their version of VNC)
and see if the problem persists with the current source.
If it still persists, run it under a debugger (or run a debugger, dbx or gdb,
on the generated core file: 'dbx /path/to/Xvnc core') and get a stack trace to
try and figure out where it's croaking which may give an indicator about what
is causing it that perhaps can be worked around or fixed in the code if it's
an actual bug in the VNC code. Post the results (stack trace) to the mailing
list if you can't figure it out yourself and perhaps myself or someone else
will have an idea.
Also, look in the vnc log file to see if there are any odd messages coming out
from the run that might hint as to what is going on before it dumps core.
Jack> Thank you,
No problem. Wish I had some more definitive answers for you.
Good luck.
Chuck
