Invalid parameter passed to c runtime
-
i don't have time to lose 8h for debugging stuff, and 30min for programming.
Perhaps you should consider another job in that case, because this is not at all uncommon.
@kshegunov Who told u i am gonna work as a programmer?

Still no check if old_strings[i] goes out-of-bounds. But using a debugger here will definitively help as it can you your the values of i,j and (if it's not a plain c array) old_strings.

With this demeanor I'm not quite sure you're going to work at all, but that's beside the point. Without enough and complete information no problem can be diagnosed or fixed.
You have denied to show us the relevant parts of the code, what variable types are the suspects involved, the stack trace - those winnt dll calls originate somewhere, they don't just fall out of the sky, and last but (probably) not least you have acted as we, the users of this forum, owe you our time.
Just to make sure that last one rings: we don't owe you, neither time, nor code, nor anything else, so don't try to act as if we do; it doesn't sit well and it doesn't help your case. We try to help other people on our own (free) time and we are not paid for it so as to feel obliged to indulge you. -

I don't wanna show anything, because it's not my point.
I found something like this: https://msdn.microsoft.com/en-us/library/a9yf33zb.aspx
Idk how to use those methods, that's why i create this topic for future, if it will happened, i will know how to find them, not to fix this particular one by showing a lot of code, and after few days it could happened again.

No body knows, how to do that?
@UnLuckyGuy
Hi, this seems to be a very hard one to debug. Do you know about these links? If not I hope they will be of some help.https://stackoverflow.com/questions/36968475/how-to-debug-invalid-parameter-passed-to-c-runtime-function

you still haven't told us jet, what the stack trace is telling you.You only wrote:
"readable" code i just created, weird stuff from ntdll or something like this
that's fine, sometimes, especially if you call system or other external libaries, the debugger can stop in the Disassembler or plain old hex text. You can go back in the call list, until you reach your own 'clean text' code.
take for example this crash:
on the first glance meaningless, but going back you a can see a QVector operation was called, bottom part of the image.
going back in the list
this tells us, a Qvector was tried to be accessed outside its boundaries. Still doesn't say much, a program can have millions of QVectors.
going back one more:
and there is the culprit. Doesn't matter much, if you don't use QtCreator, nearly all IDE's have a similar system.
