The reason I was asking: there are some scary comments in function
update_subsequent_anchors (in GridText.c), which only comes into

To quote part of the commentary:
     *   All that said, about the only time this will be a problem in

     *   after a TEXTAREA expansion), and has line crossing tag(s), and
     *   the tag numbers in a line crosser go from initially all 3 digit
     *   numbers, to some mix of 3 and 4 digits (or all 4 digits) as a

Some more scary comments in increment_tagged_htline, also only used

I don't know whether this applies in your case, but...
It would be helpful to know whether crashes also occur without

Thanks.  (It could also have been INSERTFILE, or GROWTEXTAREA, or just

You reported a while ago that you even got the question when there
were no long lines to wrap.  Does *that* still happen?

Something that might help track the problem down: make a copy
of the source of the page (the one with the textarea).  Try to
reproduce the crash with that copy.   (Don't actually submit -
At least I *suspect* that that's not needed, but going to some
other pages after the textarea manipulations may be needed to
trigger a crash.)

Maybe Kim has some better ideas.
