Description Cor Nouws 2014-09-08 11:37:02 UTC 
I'll attach a Writer document

– place cursor in front of placeholder field START (5th line)
– press Shift+Down twice (crossing page break)

doesn't crash in 4.3.1.2 > regression
Comment 3 Cor Nouws 2014-09-08 11:43:12 UTC 
easier to reproduce:
any selection with Shift+Arrow on page 2 makes the thing crash
Comment 4 Jacques Guilleron 2014-09-08 14:19:09 UTC 
Hi Cor,

I reproduce the crash with LO 4.4.0.0.alpha0+
Build ID: 37b9ea92ba81d74764a2345a9c75c65bfd272d2b
TinderBox: Win-x86@42, Branch:master, Time: 2014-08-26_09:37:01
& Windows 7 Home Premium.

This doesn't happen with LO 4.3.1.2
Build ID: 958349dc3b25111dbca392fbc281a05559ef6848

With LO 4.4, on the second page, if you change frame anchorage from Page to Paragraph, there's also no longer crash, but the selection by Shift arrow is not the same and include now the frame.

I set status to NEW.

Regards,

Jacques

Based on the facts that
(*) Ctrl-A in the attached .odt also crashes with a segfault.
(*) The crash with the STR from the bug description and the crash from
    Ctrl-A came into LibreOffice in the same day, as determinde from the
    daily dbgutil bibisect repository.
(*) The crashes on this document and the backtrace attached to bug
    82777 both show a constructor of SwNodeIndex--albeit not the
    constructor--in frame #0 of the call stack.
I guess that this is a dup of bug 82777, and I am resolving the bug
accordingly.
