gdb debug session (with more details)

The address v0 is invalid according to AddressSanitizer. This looks fishy:

#2  0x00007ffff0ae213f in lp_setup_draw_elements (vbr=0x60740000a100,
indices=0x605200001b80, nr=6) at lp_setup_vbuf.c:188
188              setup->triangle( setup,
(gdb) p i
$30 = 5
(gdb) p stride
$31 = 32
(gdb) p (ushort[64])indices[0]
$32 = {0, 0, 0, 48910, 1, 2, 4, 3, 0, 5, 3, 4, 6, 5, 4, 7, 5, 6, 8, 9, 10, 11,
9, 8, 12, 11, 8, 13, 11, 12, 14, 13, 12, 15, 13, 14, 0 <repeats 28 times>}

Playing a bit with break- and watchpoints did not really enlight me. See the
GDB session, all I know now is that something wrong entered
llvm_pipeline_generic().
