Hmm. You could check the current SVN version. There are some fixes for the DWARF loader. Also, a sync with the demangler code from gdb was recently done. Or recompile (part of the code) with different debug info generation flags of the compiler (-gdwarf-3, -gstabs, ..). What compiler/architecture is this?
