[Qt-interest] bindTexture enters in infinite loop

[Paul Wellner Bou]

Hello,

I am trying to bind a texture using Qt's methods to do so. Loading a 
QImage or a QPixmap and calling one of the different overloaded methods 
of bindTexture().

This causes the program to hang forever. I debugged it and noticed that 
it stays in an infinite loop on those lines (2346 to 2349) in qgl.cpp:

#ifndef QT_NO_DEBUG
     // Reset the gl error stack...git
     while (glGetError() != GL_NO_ERROR) ;
#endif

What does the "git" mean there?
Is this a Qt bug? As far as I know the OpenGL error flag should be reset 
to GL_NO_ERROR by calling glGetError(). There is something wrong here.

In addition to that, pausing the program, it gets stopped in line 882 of 
qstring.h (using QtCreator):

inline QString::~QString() { if (!d->ref.deref()) free(d); }

This line should not be called at all checking for GL Errors. I assume 
this is due to destructing debugging strings or similar?

Checking the error before calling bindTexture, I always get an 
GL_INVALID_OPERATION error. Although I did not do any OpenGL relatet 
stuff before, and I am not between any glBegin() and glEnd(). So the 
error check itself seems to generate this error.

Regards
Paul.
