Bug ID: 103632
Summary: Segfault during sort in ScColumn::GetCellValue
Product: LibreOffice
Version: 5.3.0.0.alpha1
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: jim.av...@gmail.com
Description:
After some macro code runs (which I can't pin down), sort segfaults.
Unfortunatly the unknown precursor operations are in BASIC macro code, so you
have to enable macros to reproduce the problem. I could not repro the crash
doing a "manual" sort which seems equivalent to what the macro code is doing.
Fortunately I have a test case which causes the segfault every time with a
single button click.
In any case, LO should never segfault, even if BASIC macros are mis-coded.
I'll attach the gdb backtrace from running with --backtrace. It starts with
this:
Thread 1 "soffice.bin" received signal SIGSEGV, Segmentation fault.

Steps to Reproduce:
1. Start LO on the attached test.ods.
2. [if necessary] Tools->Options->LibreOffice->Security->Macro Security... set
to "Medium" and restart.
3. Enable macro execution when prompted.
4. Click the "MO, TV%" button in the top middle (near column P or Q). This is
supposed to sort the sheet by Month and then TV%
Actual Results:
Libre Office crash dialog appears
Expected Results:
No crash
Reproducible: Always
User Profile Reset: No
