[omniORB] Segmentation fault in invoker.cc

[Serguei Kolos]

Hi

I'm using omniORB 4.0.7 and after moving to the SLC4 Linux (2.6.9-34, 
gcc345 compiler)
start getting crashes of my applications with stack traces showing that 
crashes happened
somewhere in the _dl_runtime_resolve call of the ld-linux.so.2 library, 
which was called from
one of the functions of the invoker.cc file. I attached two stack traces 
at the end of this
message. Here is some additional information:
1. Exact line in the invoker.cc file where crash happens is always different
2. In order to reproduce this crash I have to run the application 
several thousand
    times, i.e. this happens rarely
3. The crash always happens at the very beginning of the application, 
i.e. there are
    no incoming/outgoing CORBA requests yet
4. I run my apps with valgrind which does not detect any problems, i.e. 
it looks
    like a race condition somewhere

Had anybody observed similar problems or may be someone has an idea of 
what it might be
or how it can be investigated.

Any help is highly appreciated,
Cheers,
Serguei
