I just fixed this. There was a problem with how we were
setting the length of the array in our column_widths
method.

I haven't looked at the FLTK source code--does Fl_Browser
malloc the initial array, or is it static? Right now, if
the user passes [] to column_widths, and then passes some
other array, we would never free the earlier one, right?

One option would be that if the user passes [], we would
pass a static array (static int empty[2] = {0};) instead of
malloc'ing it.

Yes, that's right.
