My program is failing in glDrawElements,
I have found out that:
It appears that clipTEX0_RGBA0 is called with
VB->TexCoordPtr[0]->data pointing to the
texture coordinate data I originally gave
as a parameter to glTexCoordPointer.
This means bad things because the clippings
certainly don't fit into my array.
At the point of the failure the VB
seems to be the ctx->CVA.VB which
is present at the glDrawElements level.
The call stack is:
clipTEX0_RGBA0(vertex_buffer * 0x0700fe4c,
unsigned int 0x00000bb8, float 0.350644,
unsigned int 0x00000015, unsigned int 0x00000014) line 95 + 307 bytes

and the flags for the vector4f for texcoords are 0x140
(=bad stride + not writeable, which are both true...)
Of course the problem does not show up at the first
call to draw elements, and the program where it happens
has > 60000 lines of code...
