[Mesa3d-users] tnl/t_draw.c:205: bind_inputs: Assertion `inputs[i]->BufferObj->Pointer' failed.

[Utkarsh A. <utk...@ki...>]

Hi Brian,

I am trying to come up with a small test case that reproduces this issue 
that we are having with ParaView using Mesa 7.1 (as well as git-Mesa) on 
a 64 bit debian box.

The assertion fails following repeated creation/deletion of display 
lists (ofcourse when display lists are not used, everything is peachy).

For debugging purposes I put a printf as follows in tnl/t_draw.c:

static void bind_inputs( GLcontext *ctx,
			 const struct gl_client_array *inputs[],
			 GLint count,
			 struct gl_buffer_object **bo,
			 GLuint *nr_bo )
{
    ...
    for (i = 0; i < VERT_ATTRIB_MAX; i++) {
       const void *ptr;

       if (inputs[i]->BufferObj->Name) {
	 if (!inputs[i]->BufferObj->Pointer) {
	    ...
	
	    printf("i : %i\n", i);
	    printf("name: %i\n", inputs[i]->BufferObj->Name);
	    assert(inputs[i]->BufferObj->Pointer);
	 }
    ...
}

On successful runs it looks like:
i : 0
name: 1
i : 0
name: 1
i : 31
name: 1

However when the assertion fails, the output is:
i : 0
name: 1
i : 31
name: 10999

Not sure that's very helpful, perhaps you can point me in the right 
direction for producing more relevant debug output.

Thanks,
Utkarsh
