Wow -- bummer. :-(

Just to be absolutely positively sure, can you send the code? Is it
from the examples in the LAM tarball?

I'm afraid that we can't really help much here:
1. That's a *really* old version of LAM. It really isn't supported by
us anymore.
2. We have neither control nor knowledge of how Red Hat bundles LAM
with its shipping versions. You'll probably need to bring this up with
Red Hat support (feel free to CC me on the conversation; I might be
able to help with the technical content of the conversation).
I realize that this is not much of an answer, but this is like a third
party shipping my product -- I have no idea what they're doing nor how
they're doing it. :-(
