Ok, this is what I get when I set LD_LIBRARY_PATH to /tmplib/lib, and
Upon doing a gdb /bin/ps core I get the following:
warning: core file may not match specified executable file.
Core was generated by `/tmplib/lib/ld-linux.so.2 /bin/ps ux'.
Program terminated with signal 11, Segmentation fault.

I don't know if that does you any good. It seems like a weird place
to die when doing a ps.
Any ideas on how I should proceed?
How do I use gdb to load an executable, with a different set of
shared libraries? [I've tried setting the environment, and also
having it run /tmplib/lib/ld-linux.so.2, but it complains about
In any case, if I run /tmplib/lib/ld-linux.so.2 /bin/ls -al,
it segfaults in the exact same spot.
[here's a backtrace for this case..]

Let me know if there's anything I can do.
I have to go to work, so I'll start looking at source tonight or
