About debugging (again)

[ANtlord via Digitalmars-d-learn]

Hello! I've met an issue related to debugging by GDB. Directly 
when I try to show call stack I get like this 
http://pastebin.com/kRFRqznq. How can I make name of methods more 
human readable?

I see part of printed name matches to name of methods from code 
and I can suppose what method was called, but it would be great 
if I can debug application without any supposing.

Sorry if my english is not clear.
