Bug ID: 86316
Summary: VIEWING: crash upon zoom-out
Product: LibreOffice
Version: 4.4.0.0.alpha0+ Master
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Keywords: regression
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
STR
(1) Run LibreOffice with command line parameter --writer. The program
displays Writer window "Untitled 1". The ruler to the left of the
document area extends to about 17.5 cm at the bottom of the
screen.
(2) In the zoom control in the status bar, click zoom-out three times.
The ruler at the left of the document area extends to about 24.5
cm at the bottom.
(3) In the zoom control in the status bar, click zoom-out. The
program crashes. Last message in terminal is:
*** Error in
`/nb/downloads_libreoffice64/lo-daily_20141114/opt/program/soffice.bin':
free(): invalid size: 0x00000000017d88c0 ***
Note:
(a) The crash happens with the zoom-out which would display the whole
page in the document area. The particular measurements in the STR
depend of course upon my screen.
(b) If you start with zoom-in's, you need that many more zoom-out's to
make the crash.
(c) When I edit an old .odt file, I can zoom out without problem. If
I save that document and reopen it, zoom-out again crashes.
However, it is definitely not the case that that every document
saved from daily dbgutil version 2014-05-21 is immune from a crash
upon first open in version 2014-11-14.
(d) The soon-to-be attached terminal output and backtrace are from the
simple steps I described above. A longer scenario (I was *of
course* trying to reproduce another bug report) resulted in a
segmentation fault.
(e) I used a new user profile before starting the bibisect. Al
subsequent tests use that same user profile.
Working in the daily dbgutil bibisect repository, I see from `git bisect good`:
