I know that noreturn attribute is for code reduction. It is obvious that
functions like abort(), exit() should be declared with this attribute.
But (in some case, in my case embedded system) it can make coding and
debugging make more difficult. Since asserts are mostly used  in debbug
bulds, there could be some way (maybe addtional __assert_func_returning
function ) to use assert() macro without noreturn attribute.

Do not take me wrong, I am not insist about this, but this was my
observation when I had to refactor whole my code to provide custom,
nonstandard assert() macro to show when my code is failing becouse stack
trace was broken.
