I have find where is the problem (with optimisation -O2) in my case
with the libosg.dll
this line [0 0x100b0492 in __static_initialization_and
_destruction_0(int, int) (
__initialize_p=269417824, __priority=2292424) at
../PointSprite.cpp:73]
in gdb has help me.
if I change the PointSprite.cpp:line64 file and I force to jump
the detection, it works correctly.
bool PointSprite::isPointSpriteSupported(unsigned int contextID)
{
// if (!s_extensions[contextID].initialized)
// {
// s_extensions[contextID].initialized = true;
// s_extensions[contextID].supported =
isGLExtensionSupported(contextID, "GL_ARB_point_sprite") ||
isGLExtensionSupported(contextID, "GL_NV_point_sprite");
// }
// return s_extensions[contextID].supported;
return true;
}
???
This function must not be compiled with -02 option,
perhaps it is isGLExtensionSupported witch crash, I don't know why
exactly.

Hi Andreas,
this is interesting. On my machine it crashes in debug
version, too. Did
you do anything special to build the debug-version? I just
used "make
debug" for OpenThreads, Producer and osg (and make install, of
course).
Or did you only build the debug-version of osg and left the
others in
release?
I have just use a make debug on the OpenSceneGraph directory. The
rest of OpenThread and Producer
is in release target. To success to compile osg in debug mode, I
have change the powf call to pow in osg/src/Image.cpp 275 else I
get a link error on this function.
However I have adapt the example with my framework to run and be
deployed on the win32 pc but it is the same example code.
My debugger version is
i586-mingw32msvc-c++ -v

As I said, I don´t get a correct backtrace, because it seems
that the
application goes into an infinite loop in some module that is
not in
debug-mode (maybe opengl32.dll?).
I haven't constat an infinite loop but the program exit anormaly
in my case
and I don't arrive to understand what he gdb windows version said
exactly.

And: Do you use the libopengl32.a that is provided with mingw?
I tried
to link directly to the microsoft-lib ( opengl32.lib), but
that didn´t
work. I thought that there might be an incompatibility with the
mingw-lib and the microsoft-dll.
I use only the libopengl32.a,
it is not a good idea to use a .lib, for me it doesn't work
correctly, make it only if you have not the choice.
