They are not the same issues.

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



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.
