I grabbed svn r13265 twice. First copy I compiled with no other
patches applied. Second copy I compiled with only 3031-dbg-2.patch
applied.
I installed the non-patched version first. It took 19 attempts to get
it to fail.
I installed the patched version and attempted to make it fail 115
times. It did not.
I re-installed the non-patched version. This time it only took 6
attempts to get it to fail.
I am attaching two logs. One is the result of the failure. The other
is an example from one of the patched attempts.
