> Suggested patch implements new heuristic algorithm for native stack unwinding.
> This algorithm enables quite correct stack printing for x86_64 platform.
> Internal crash handler interfaces are simplified and improved.
> There is a problem with line information on Windows x86_64 - I'll try to solve this in separate JIRA.
> All pre-commit tests are passed for me on 4 platforms.
> Crash stack examples are attached.
