egcs 1.0.3 still has non-thread safe exception handling. This make it
unusable when the setjmp/longjmp is used to implement exception handling on
the platform. I think/guess is the case with SGI falls into this category.

The current egcs development snapshot is purported to support thread-safe
exception. I've been using egcs-980302 successfully on x86 Redhat 5.0. On
alpha linux it is still a no-go. I don't know if it works on SGI.

The random crash you are seeing is consistent with what I observe on alpha
linux and is related to whether exception-handling is thread safe.

If you can use SGI's C++ compiler, there is some hope to get omniORB2
running. See my next posting.
