I take it that you did a sanity check on it, and trivial executables
compiled with it run fine?

No further clues here :(

You'll need to either find IA64 platform guru (such people are rare),
or come up with a small test case which reproduces the problem.

You may also try to build your code with HP aCC, or with a different
version of g++, and see if the problem persists. If it does, it
is quite likely that the application is corrupting the runtime
loader ( in which the crash is happening) data.

If that's the case, you could try tools like Insure++, or you
might try porting to Linux/AMD64 (a much more programmer-friendly
platform), where Valgrind is also available.

In order to understand recursion you must first understand recursion.
