Re: GC bug?

[Richard M. Stallman]

    I made a diary entry and then called calendar and Emacs immediately
    hung or went into an infinite loop, presumably in diary-list-entries,
    since the last message was "Preparing diary...".  I could get out of
    the loop by typing C-g.

Then it probably isn't a GC bug.  It is probably an infinite loop
that does a lot of consing and therefore frequently GCs.

I suggest you stop it outside GC with a breakpoint at Fgarbage_collect
and then type `finish' to get over the GC.  Then please follow the
methods suggested in etc/DEBUG for debugging infinite loops.
