Better error message for endless recursion (or other segfaults) on linux

[ryuukk_]

Better error messages is always nice to have thanks for your PR

I wrote a piece of D code few month ago that does print 
stacktrace on various segfaults (both windows/linux), would be 
nice to consolidate everything and have this built-in, so D gets 
a nice debugging experience out of the box

Zig goes this as well, and it pretty much is a nicer experience 
overall

cleaned up, but does the job)
