Compiler optimization issue (/Od)

[underflowerror]

Hello.
First of all, thanks for creating this library it's really helpful.

Library works great with /O2 compiler flag (thats default option for a new project), but problem comes with /Od flag and /Ob1.

As you can see everything is fine, except fact that our original integer is shown and not even used. This issue persist in any variable type. This library works great with those flags, thing is that library supports only strings.

Thanks.

Thanks for your reporting,
Optimization must be enabled, and this problem may be due to some parameter passing
