Before I lived in assurance that asserts are actual only in debug mode 
and in release mode they are nothing (except `assert(0)`). But today my 
whole life is going sour because I stumbled upon assert in release mode 
and of course that assert is failing.

This doc https://dlang.org/spec/expression.html#assert_expressions say 
nothing about debug mode vs release mode.

So the question is when and why assert expression is enabled in release 
mode (besides assert(0))

There are also other switches like -boundscheck and -check. It’s 
possible you have some library or project that is causing the 
behavior.

Thank you, Steve.
In my case I guess it was my mistake because now I returned to the 
problem to fix it and I can not reproduce that behavior locally.
