QGLShaderProgram works on Debug mode, fails on running in Release.

[escobar]

That's even more strange... if I disable Shadow Build it doesn't run:

The program has unexpectedly finished. ...Test3.exe exited with code -1073741515

Edit: I found that this means that is missing some libs, it happens since disabling shadow build it is placed in another directory, after putting that dlls there I have the same "bool __thiscall QGLShaderPrivate::create(void): Could not create shader of type" error.

So that didn't solve nothing but thank you for your time anyway.
