[omniORB] Segment fault on Redhat 5.0

[zeng xibai]

I am new to omniORB2.7.1. After I complied it and try to run
omniNames
as follows:

% export LD_LIBRARY_PATH=/omniORB_2.7.1/lib/i586_linux_2.0
% export OMNINAMES_LOGDIR=/tmp
% /omniORB_2.7.1/bin/i586_linux_2.0/omniNames -start 12345&

it does anything and return an error:
     [1]+  Segmentation fault      ./omniNames -start 12345

My platform is:
RedHat 5.0 on x86
gcc version 2.7.2.3
g++ version 2.7.2.3

thank in advance for any kind help.

best regards,
