backtrace

The latest build of the game Torchlight segfaults on start with Mesa 9.0 or git
master. The crash happens in  BlitNtoNCopyAlpha () in SDL2, but only if the
game is set to launch full-screen.

Bisecting finds this commit:

0671400dcc72553b5f9719639e86069a1734dbe5 is the first bad commit

I tried reverting this on master but it seems dependent on other changes, so it
doesn't build. OTOH, the commit immediately prior to this one,
74027a9ba250f07a77ee40e105c50c27e4fc3bc0 is working so it's probably the right
one.

I'm not sure if this is a driver problem or a bug in SDL, considering that
earlier builds of the game worked fine with Mesa 9.0.

--- Comment #1 from Sven Arvidsson <sa@whiz.se> ---
This is still a problem with Mesa 9.2 and the game build from 2013-05-21, but
something has changed, now I get a BadDrawable error and the game exits so
there's no crash or backtrace to get:

X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  137 (DRI2)
  Minor opcode of failed request:  3 (DRI2CreateDrawable)
  Resource id in failed request:  0x3800002
  Serial number of failed request:  23
  Current serial number in output stream:  25

Reassigning to mesa core as this has also been reported on i965.
