Description Mike Kaganski 2020-04-16 07:46:50 UTC
1. Open LibreOffice; create a new document (e.g., a text document, or a spreadsheet)
2. Tools->Macros->Edit Macros

  => the cursor is automatically in Object Catalog's "My Macros & Dialogs/Standard/Module1"

3. Press Ctrl+End

  => CRASH.

When bisecting, sometimes in bad builds, on Ctrl+Enter it moved to the last entry Untitled 1's "Standard" subelement; collapcing it, then selecting initial node again, and repeating Ctrl+End crashed it. In good builds, it always moved to Untitled 1 without expanding it.

Regression after

The problem seems to be that when it moved to the last entry, it selected that entry in SvImpLBox::m_pCursor, then detected that it's dummy entry in IMPL_LINK_NOARG(SalInstanceTreeView, ExpandingHdl, SvTreeListBox*, bool), deleted it (but the m_pCursor in m_xTreeView->pImpl was kept)...

Forgot to mention that it was experienced and bibisected on Windows.

On pc Debian x86-64 with master sources updated today, I could reproduce this with gen rendering (not with gtk3)
