Re: error in calendar

[Richard Stallman]

    On trying to find out where the problem could be, I used an evaluated
    version of mark-visible-calendar-date and the problem disappeared.
    (Such a behaviour has happened to me before: with compiled code, it
    gives an error, while it works with evaluated code.  I have not been
    able to find out what the cause might be.)

This is very disturbing.  I think it is important to track this down.
I just read the code of that function but did not see anything that
looks like the compiler could not handle it right.

Please try M-x disassemble on mark-visible-calendar-date, and compare
the output with the source code.  Does the byte code correspond
correctly to the source code?
