Hi,

I noticed that vm is now in the trunk, so I decided to run some benchmarks
to test it for robustness. While doing this, I found a problem that seems
to be related to continuations, although guile crashes in gc. I have
attached a minimal and self-contained testcase here. Note that iterating
50 or so times is required to trigger the segfault so that is not "extra
code".

I have also found problems with other tests from the same benchmark, and
at least one of them is using call-with-current-continuation also (others
I have not looked at yet). I will report them as well, but right now I
don't have reduced testcases for them and they are likely duplicates.

Best Regards,
Juhani
