I am now getting a SEGV presumably in a garbage collection routine (gc_mark)
on trunk (SVN revision 28656), but about 15 hours ago I didn't. I don't get
the crash every time I run "make check" but in 1 out of 3 tries I do.
Attached should be a slightly stripped down log of a "make check" run from
Ubuntu.

Thanks.
