Bug ID: 94429
Summary: CPU-bound hang opening spreadsheet
Product: LibreOffice
Version: 5.1.0.0.alpha0+ Master
Hardware: Other
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-bugs@lists.freedesktop.org

Test spreadsheet which make LO "hang" when loading
Using 5.1.0.0.alpha1 on 64-bit linux (Ubuntu 15.04)
Something horrible happens with the attached .ods spreadsheet which pegs the
CPU and prevents LO from functioning normally. When first opened, a blank
window is displayed for maybe 30 seconds; then the spreadsheet view is painted,
bit by bit, and after a couple of minutes it all seems to be showing. However
LO is unresponsive and the CPU remains pegged at 100%.
=> This spreadsheet functions perfectly using Apache Open Office 4.4.1
lo 4.4.2.2 opens the spreadsheet quickly, but if macros are enabled it crashes
during certain operations. I didn't get far enough to try the macros with 5.1
alpha1, since I can't even load the spreadsheet with macros DISABLED.
STEPS TO REPRODUCE:
1. Start lo on the attached spreadsheet
2. When prompted, DISABLE macros
EXPECTED RESULTS:
Spreadsheet displays promptly
ACTUAL RESULTS:
Spreadsheet "never" displays, and CPU stays pegged at 100%
NOTE/IDEA/CONJECTURE: This .ods file contains several dozen "sheets", each of
which contains a few lines which use Conditional Formats to change the color
and possibly font size of affected cells, depending on the data. Maybe the
problem has something to do with that.
