gdb seems to be having trouble reading some of the DWARF information in your project.
You can narrow this down by putting:
set verbose on
in ~/.gdbinit then rerunning the debugging session. Look in the console and gdb will write out the name of each .o file as it is ingesting it. The last one you see before this crash will be the one that is causing the problem. Once you locate the offending .o file, if you don't mind sharing that with us, then please file a bug and include the .o file that is causing the problem and we'll take a look.
You might try switching compilers to see if the compiler is causing the problem. That way at least you'll have a way to work around it till we figure out what is going wrong.

I just can't imagin what I might touch in the system, but now it fails to start the debugging process in the Debug target (though starts it in Release target) . I didn't change anything in targets options since last successful session. Of course, I changed the project source code itself.
