Re: segfault caused by rmail-delete-backward

    OK, you shamed me into downloading & compiling emacs 21.2.  The error
    is in xdisp.c, line 14291:

It would be more useful to debug it in the current development
sources, because that way we could see if it is fixed already.
However, this line

     while (*cursor != '\n' && ++cursor != ceiling_addr)

still exists, so it is possible the problem is unchanged.

To start to understand, I need more info.

What is the value of ceiling_addr?  What was the initial value
of cursor?  What is the value of cursor when it crashes?
What is the value of ceiling?

    Does anyone really run emacs under GDB *all the time*?!

I do.
