I just got a segfault, this time on MS Windows (if that should
matter).

I need advice on how to track that bug down or at least how to
provide better information.
This is not the first time that I have a segfault with these
symptoms. What should I do the next time?
This bug is not easily reproducable. Is there a way in gdb to dump the
memory image of a process to a file and restore it later? So that I
can answer questions to you, if necessary, after I reported a segfault
at any later time?
