Hi George,
This first showed up on one of our older dashboard machines without AVX
(Nehalem processor). You can easily reproduce it by building with
--with-swr-archs=knl,skx when the machine you're trying to use it on is
neither. Note that dri-glx seems to handle this case just fine but
xlib-gl
I believed I created the same failure by deleting libswr*.so, however in my
case (running glxgears) I hit a SEGV in XMesaCreateVisual (calling
xmdpy->screen->is_format_supported()), because xmesa_init_display() created an
xmdpy with a NULL screen. I never get to the xmesa_close_display().
Were
Chuck,
In which cases do you hit this? When an architecture is not supported, then
swr_create_screen() falls back to a different (older) architecture.
Thanks,
George

This fixes a segfault exposed by a29d63ecf7 which occurs when swr is
used on an unsupported architecture.

This fixed a segfault exposed by a29d63ecf7 which occurs when swr is
used on an unsupported architecture.
