I have confirmed this as well. I have no clue if this will be addressed as it's so specific to a particular macro enabled page that I personally have no clue what it's intended purpose is. 

Markig as NEW and prioritzing:

Major: I'm hesitant to mark this as Major but since it causes a crash, I'm going by my normal flowchart and marking it as so.

Lowest: So specific that it's unlikely another user would have face this furthermore there is a workaround to just go slow.

If someone could do a bt that would be nice, I may be able to do one tomorrow.

at the bottom of the stack we have m_aDataArray.clear() but *mile* up the stack in frame 110 we have...

Item& rItem = m_aDataArray.back();
rItem.maString = m_pDocument->GetString(aAdr);

so during the GetString the m_aDataArray is cleared, so rItem is no longer valid and we cannot assign to it anymore legally

With the straightforward approach of http://cgit.freedesktop.org/libreoffice/core/commit/?id=deed6dcacd355ce84cada955887a31e7d8cb5fb1
it no longer crashes.
