GDB wrote: "Reading symbols from /usr/local/debug2-chessd/chessd/./lib/chessd.so...done." The path is very strange, 'cause .so lays at "/usr/local/debug2-chessd/chessd/lib/chessd.so", not in "/usr/local/debug2-chessd/chessd/./lib/chessd.so". But reading is done. OK. So what that means: "0x2ac73c in ?? () from /usr/local/debug2-chessd/chessd/./lib/chessd.so". If GDB read symbol table, why function is: "?? ()"?? 'list' command in this case showed rubbish too.

P.S. All files that is included in .so was compiled with gcc '-g' flag.
