Some more debugging info (still from texdown):
(gdb) print count
$13 = 3
(gdb) print ((TNLcontext *)ctx->swtnl_context)->clipspace->attr[0]
$14 = {attrib = 0, format = 6, vertoffset = 0, vertattrsize = 16,
inputptr = 0x8207b90 "", inputstride = 16, insert = 0x3b0d0db0,
emit = 0x3afeb3a0 <insert_4f_3>, extract = 0x3afec7d0 <extract_4f_viewport>,
vp = 0x808cd90}
(gdb) print ((TNLcontext *)ctx->swtnl_context)->clipspace->attr[1]
$15 = {attrib = 3, format = 15, vertoffset = 144, vertattrsize = 4,
inputptr = 0x80614ec "", inputstride = 0, insert = 0x3b0d0eac,
emit = 0x3afeb910 <insert_4ub_4f_rgba_3>,
extract = 0x3afec990 <extract_4chan_4f_rgba>, vp = 0x808cd90}
(gdb) print ((TNLcontext *)ctx->swtnl_context)->clipspace->attr[2]
$16 = {attrib = 8, format = 3, vertoffset = 16, vertattrsize = 16,
inputptr = 0x81f2954 "", inputstride = 16, insert = 0x3b0d0d5c,
emit = 0x3afeb4b0 <insert_2f_2>, extract = 0x3afec8a0 <extract_4f>, vp =
0x808cd90}
(gdb) print VB->AttribPtr
$17 = {0x0, 0x81f69ec, 0x81f6a08, 0x81f6a24, 0x81f6a40, 0x81f6a5c, 0x81f6a78,
0x81f6a94, 0x81f6ab0, 0x81f6acc, 0x81f6ae8, 0x81f6b04, 0x81f6b20, 0x81f6b3c,
0x81f6b58, 0x81f6b74, 0x81f6b90, 0x81f6bac, 0x81f6bc8, 0x81f6be4, 0x81f6c00,
0x81f6c1c, 0x81f6c38, 0x81f6c54, 0x81f6c70, 0x81f6c8c, 0x81f6ca8, 0x81f6cc4,
0x81f6ce0, 0x0, 0x0}
So, the first pointer (for attrib 0 (position)) is the NULL pointer leading to
the segfault, the other ones (attrib 3 (color0), attrib 8 (tex0)) look rather
reasonable (?). Unfortunately I'm no tnl wizard...
