Bug 169064

Description of problem:

When I leave off some of the -lXblah arguments, the dynamic linker manages to
find everything OK, but depending on position, the program segfaults or
otherwise doesn't work.  When I fully specify the link order, it still sometimes
doesn't work, if the order is wrong.  I have found an order that always works,
but there's still some strange position dependent bug.  I haven't tried linking
statically.

Version-Release number of selected component (if applicable):

I've tried this on two very different boxes, both x86, running FC4 that was
completely up to date (yum update done prior to all tests, and xorg-x11 has had
a few changes recently so I made sure I was getting the latest, as of 9/22).

How reproducible:

Very, but unpredictably, depending on link order.

Steps to Reproduce:
1.  Sample program below.
2.  Compile and link; experiment with library order, like leave most of them
off, or just try something like -lGLw -lGL -lXt -lX11 -lXm; some combinations
work, some don't.  I get segfaults, or invalid X requests, depending on how it
links.  Even re-running it can change what I get (different dynamic link order).
  
Actual results:

segfault

Expected results:

no segfault
