The trunk can detect this with the reduced testcase in comment #16 with
-fsanitize=address (it could not in GCC 12 though):

Marc:
struct Iter
{
Iter& operator+=(int) { return *this; }
int operator*() { return i; }
int i;
};
Iter& func(Iter iter, int n) {
return iter += n;
}
int main()
{
Iter iter = Iter();

If you can reduce the testcase to a manageable size, I'll see why
https://gcc.gnu.org/ml/gcc-patches/2014-06/msg01692.html is not enough (it
should be, with -fkeep-inline-functions, but is apparently missing a

Yes, I can't convince gcc or clang to give a warning. Even address sanitizer
and undefined-behaviour sanitizer don't catch the problem.

I'm sorry that i made you lose your time :-(
I thought that kind of code would trigger a warning though.

Sorry, temporary is the wrong word - a reference to a local

Well, the default assumption, when someone posts a 77000 line preprocessed
program with strange runtime behavior, is that the program is buggy.
You have to convince us that the error is on the compiler

I also wanted to say, my code may be not optimal or may be done in an easier
way or else (and if you have comments on it i'm ok with that), but what i think
what is the most important here is that it seems t

It's a type i created to be able to store data that does not fit in ram, with

But i removed most of it to simplify the problem search for you, even if i did
