Shared Arena Base troubles

Hello,

I'm having trouble getting the Performer Shared Arena Base to go where I
told it.

I have an Ada application that links in a simple Performer C file which does
Line of Sight functions. The C file does a pfInit(), loads the database,
and subsequently returns true or false on LOS between two points.

Since we make use of many SGI arenas, I need to specifically locate the
Shared Arena to keep it from stomping on other arenas. No matter which
address and size I put in pfSharedArenaBase() and pfSharedArenaSize(), the
system finds a different place for it. It even varies between runs.

I have a little better luck linking everything together into a C executable,
so I'm wondering if it has something to do with the Ada executable.

How can I find out whats causing the arena to not go where I told it?

Thanks for any help,
Erik
