Bug ID: 94146
Summary: Segfault getting accessible object attributes in Calc
cell with formula immediately upon launch
Product: LibreOffice
Version: unspecified
Hardware: Other
OS: Linux (All)
Status: UNCONFIRMED
Severity: major
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]

--> https://bugs.documentfoundation.org/attachment.cgi?id=118624&action=edit
accessible-event listener: soffice-events.py
Steps to reproduce:
1. Launch the accessible event listener in a terminal
2. Open the attached test case
Expected result: Calc wouldn't crash.
Actual result: Calc crashes fairly often.
There seems to be a timing issue. In terms of real-world use, if you launch the
document with an assistive technology like Orca running and you do not press
any arrow keys immediately, Calc doesn't crash. As a result, the event listener
is synthesizing several up and down arrow press and releases as soon as the
frame becomes active. This seems to increase the likelihood of reproducibility.
The Orca user who reported this issue indicated that having Thunderbird running
helps make the crash occur. While I've not seen any difference in that regard,
I have found that running LibreOffice in gdb greatly improves the changes
you'll get the crash.
That said, if the crash doesn't happen, leave the event listener running, quit
Calc, and re-open the attached test case. I've been getting the crash within 3
tries without gdb, and it reliably crashes every time for me when run in gdb.
