HI Jesper,
That killer doc I sent you no longer asserts on loading but it
does segfault inserting page numbers.
stack trace follows:

<snip more higher level stuff>
You got bitten by the fp_Line = NULL in fl_hdrftrSectionLayout blocks I
think.
Further stress tests I can suggest after you fix this.
1. Try changing the page sizes in that doc after you inserted
headers/footers. Change A4 = > A6 > A0 > A4 > landscape > A0 > A6 >
portrait > A4.
2. Try changing the left/right/top/bottom/header/footer margins with both
a header and a footer in that killer doc.
Good Luck!
Martin
PS. We really want Bob Seivers to come along and find ways to crash your
code.
