Ok I've tested the patch on Quantal and it does indeed fix the issue. I
was able to even increase the number of iterations in the reproducer to
10 and not incur a crash. In addition, I ran this multiple times.

The attached patch (done against natty), seems to address the issue. It
specifically addresses the recursion of free_profile that is causing the
stack corruption.
A test kernel with the patch applied can be found at
http://people.canonical.com/~jj/linux-image-2.6.38-16-server_2.6.38-16.67~lp105607
Yes, this bug is present on the latest kernel.

Attached is a reproducer script used to trigger this bug. You can
increase the number of iterations if it doesn't crash your system.
