Hi, after I had a hard time looking at code dumps it turned out that gcc 2.95.3 on Solaris 7 has optimizer problems that poped up in my omniORB application. The g++ compiler is so buggy that STL libraries crash when omniORB is under heavy load. Some of the omniORB templates crash also and the only workaround this is to force no optomization at all... (-O0 switch). Regards, Ivan
