Jose, I think it would be more symmetric with the peer
setup_ff_generate_mipmap() function if we just enabled the vertex arrays when
we create the vertex array object. So, how about this patch:

I suspect the problem are these lines in setup_glsl_generate_mipmap():
_mesa_BindAttribLocation(mipmap->ShaderProg, 0, "position");
_mesa_BindAttribLocation(mipmap->ShaderProg, 1, "texcoords");

Sounds like the glGenerateMipmap implementation (likely Meta module) is
clobbering the GL_VERTEX_ATTRIB_ARRAY_ENABLED* state.

The link to the trace doesn't work. Can you attach the trace to this bug
report?
Which Mesa driver are you using?

I've had another look at the trace created with apitrace. And it looks like the
issue is caused by glGenerateMipmap(GL_TEXTURE_2D). It seems to use the first
and second vertex attribute array, but doesn't dis

--- Comment #2 from cor...@gmx.net ---
A workaround for the segfault is to explicitly disable vertex attribute arrays:
GLint n = 0;
glGetIntegerv(GL_MAX_VERTEX_ATTRIBS, &n);
for (GLint i = 0; i < n; ++i)
glDisableVertexAttribArray(i);
Which i
