 Not for now.

 Is it good? Can we take ideas from it?

 It using the same StackWalk64, just resolves addresses with debug
 information generated by GCC using specific libs. Overcomplex mix by run-
 time code and size of result.

 Better to have proper stack trace with valid RVAs that user could to
 report. For proper resolve address-to-function-name we could to use gdb
 (at least it worked for mingw port) during investigation a bug. Debug info
 with symbols can be saved per package, like gitian-based builder does it
 for linux bundles now.
