--- Comment #9 from Chris Wilson <chris at chris-wilson.co.uk> ---
>From within gdb, after the break due to the segfault, either type "frame 2" or
"up" twice. Then type "p *priv", "p *priv->cpu_bo", "p *priv->gpu_bo". And hope
gcc hasn't optimised away priv. If it complains that priv is not available, try
"p *sna_pixmap(pixmap)", "p *sna_pixmap(pixmap)->cpu_bo", "p
*sna_pixmap(pixmap)->gpu_bo". (And cross your fingers.)

A last resort would be --enable-debug=full and hoping the error still occurs.
The Xorg.0.log will be massive (may even be greater than 2GiB) but only the
last 1000 lines will be enough to check to see if the bug exposes itself.
