Yeah, that works fine. But:

If you select Rotem's article three times (jumping out of the backtrace
the first two times), Emacs will segfault the third time. It seems to
be totally reproducible for me.
I don't know how much of the valgrind output to include. It's 15K lines.
Before the crash, I get lots of the following:

Then when it actually crashes, this is what's output:
valgrind: m_mallocfree.c:294 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi'
failed.
valgrind: Heap block lo/hi size mismatch: lo = 65541, hi = 489626271855.
This is probably caused by your program erroneously writing past the
end of a heap block and corrupting heap metadata. If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away. Please try that before reporting this as a bug.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.
If that doesn't help, please report this bug to: www.valgrind.org
In the bug report, send all the above text, the valgrind
version, and what OS and version you are using. Thanks.
