issues with release mode

[mirswith]

I am using libvlc and the debug version of my app works fine however the release mode abruptly crashes with my first call into libvlc, i've tried calling libvlc_get_version as well as libvlc_new first both have the same issue. I posted another message about delay loading the dll here viewtopic.php?f=32&t=97013 but I am not sure if it is related. Unfortunately being in release mode I do not have any good information to help me pint point the problem.

Things i've checked/tried:
- The same compiled dll's work fine with the vlc app from the same build.
- The address to libvlc_get_version is not null.
- I've tried loading the dll's directly with LoadLibrary.
- tried removing all the plugins.

I'm not quite sure what else to try here but could use some pointers.

Thanks.

This is usually due to mismatched calling conventions.

How can I test this is the case and more importantly fix it? I'm using QtCreator to compile my app with a VS 2010 backend. I am using several other C libraries in my app and am not having this issue there, i'm at a bit of a loss.

Thanks for your help.

I've found adding /INCREMENTAL to my linker flags makes the issue go away, but why would this make a difference? Here is info about the flag http://msdn.microsoft.com/en-us/library/4khtbfyf.aspx

Had the same problem, though maybe a different cause as the solution was different;
Release configuration must be <OptimizeReferences>false</OptimizeReferences> [Linker \ Optimization \ References = No (/OPT:NOREF)]

Just verified /OPT:NOREF also fixes it for me as well. It would be nice to understand why either of these fixes the issue, any ideas?

Not sure... MSVC is a black box
