They are not the same issues.

And I found this is not a regression bug for on  the commit
Mesa: (7.11)c0009739bf65883c780408e252c6bdc76f56aecb
this issue is also exist.

What's the difference? Or do you mean you can't reproduce bug#36070?

Comment 4 Kenneth Graunke 2012-05-31 17:08:11 UTC

In case people aren't aware, "texleak" is from the Mesa demos repository:

ssh://git.freedesktop.org/git/mesa/demos

src/tests/texleak

And yes, it does give me a "bus error" on SNB.

Comment 9 Ian Romanick 2013-06-19 08:25:44 UTC

I just cherry picked the relevant patches to the 9.1 branch.  This should be fixed as of commit 060f7b0.  This will be in 9.1.4.
