gcc options craches binaries about k2

[serg-meus]

I suppose, you forgot the -pthread option.

-pthread not needed for msys2 mingw... in this case we used Windows threads, otherwise POSIX
but with -pthread binary crashed too with -flto:

P.S. а варнинги не красивые с кастами и перекрытием(зетемнением в стеке) аргументов...

Hello!
Could you also add the '-g' option, compile, run and send me a crash dump?
P.S. Yes, there are many ugly things in the code. I'm a hobbyist developer so thank you for pointing them out.

[d3vv]

I've got it about hobby... But where i can get a dump(core-dump)?

$ cat Makefile.FLTO

sorry about previous post

There is a problem with -static + -flto options
