Here the point is! I don't have "classic" shared libraries like 
libxxx.so. And application is not linked with them.
I have xxx.so and load it via dlopen function. I.e. gdb doesn't have
any knowledge about c++ files in my shared object until I type in "sharedlibrary" command!

I tried solaris8-intel and solaris8-sparc platforms with ulimit=unlimited.
