Something wrong with generation debug info.

Case 1. CV debug info

Same executable, MS WinDbg X64 works, may set breakpoints in 
opened source code, step by step debugging works.
Also Windbg commands worked fine bp Dmain, bp d_throw_exception 
working (without leading underscore!)


Case 2. Dwarf debug info
