[omniORB] RE: Problem with IRIX 6.3

[Sai-Lai Lo]

Nilo,

As a general advice to all Irix users, it is best to apply all the patches
SGI supply for the C++ compiler and anything related to pthread. Otherwise
it is almost certain that omniORB programs would crash.

Back to your question, your stack trace indicated that eg2_clt completed
the call successfully, so it exits and the connection is closed. A thread
inside eg2_impl sees the connection closed and throws a COMM_FAILURE
exception. This is normal. The exception is caught in a try block before
the thread exits orderly. The stack trace seems to indicate that the
compiler runtime failed to locate the try block and hence decided that the
exception was not caught and so called abort.

Looks to me it is a compiler bug.

Regards,

Sai-Lai
