Firstly, want to say that I'm not looking for elitest posts saying std::string sucks and I should use <input any other lib here>. I'm using it and I'm not changing. So if you have nothing to input that will help, don't post.

Anyway, the issue is, when I turn full optimization on, the first two strings that I have using std::string to print text to a DC work, but any other strings after that are gone. As if their values are nulled out without reason.

Turning off full optimization works fine. All the strings are printed fine.

Screenshots of what I mean:

Normal compile with no optimization. (Can achieve the effect with custom optimization but not with full.)

Full optimization.

Other parts of the project use std::string but all work fine later on, only the ones drawn to the screen are being "corrupted" if you will.

Anyone else seen this before, or have a fix? (I really wish to use full optimization so looking for a solution to be able to use it.)

Haven't come across that before and I use std::string a fair bit, strange..

Mind posting the snippet of code that renders the strings? Or a replicate of it.

The code that paints the text is an ASM static lib. Which I use because:
1.) I can't convert it to C++ (Uses MMX functions and such.)
2.) It creates alpha blended text for other methods of drawing.
3.) Various other small reasons that aren't important.

Theres not really anything I can post it though, as the project is a dynamically driven GDI engine. The text objects are a single reusable class that is vectored for each string object thats loaded into the GUI.

(And no PaintText is not an API.)

I see what you mean. The code doesn't help at all in this case lol.

The only thing that I can think of that would be remotely relevant is that the for loop isn't indexing the entire m_vTextObjects size. I'm guessing you've already checked to see if the size is different between optimization modes?

Other than that, I'm quite stumped. :\ Sorry I couldn't be of much help. If something pops into mind, I'll post it as soon as I can.

Are you using -02 or -03 for full optimization? I've heard -03 can do wonky things and generally isn't that helpful.
