log of the build process

I'm using Gentoo Linux an an amd64 box with gcc-4.7.0. When building mesa I see the following buffer overflow error in the test suite.

[ RUN      ] glXCreateContextAttribARB_test.NULL_display_returns_None
*** buffer overflow detected ***: glx_unittest - terminated
glx_unittest: buffer overflow attack in function <unknown> - terminated
Report to http://bugs.gentoo.org/
/bin/sh: line 5: 13934 Killed                  ${dir}$tst
FAIL: glx_unittest

I first reported this issue at [1]. If any further information or action is required please tell me.
