Ok.  Until someone actually has details, I don't see any reason to post
more "me toos".

I really do trust that Volker is not crazy and is reporting a problem.
Random stack dumps are not a good thing and it is something that we
want to fix but if you can't provide any more details than "I saw one,
too!" then "I can't provide any info, but me too" email is not any
help whatsoever.
