Summary: FILEOPEN writer crashes with SIGFPE when opening doc
file
Product: LibreOffice
Version: LibO 3.3.2 release
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: critical
Priority: medium
Component: Writer
AssignedTo: [email protected]
ReportedBy: [email protected]
On an Ubuntu 11.04 live system, trying to open a certain doc file makes
LibreOffice crash while importing. Unfortunately, I cannot provide steps to
reproduce since I cannot publish the file. By the way, opening the file with
Wordpad on Windows XP also fails.
The problem seems to lie in the function SetDocumentGrid of libmswordli.so, as
reported by gdb:
Program received signal SIGFPE, Arithmetic exception.
0x061c9dc6 in SetDocumentGrid ()
from /usr/lib/libreoffice/basis3.3/program/libmswordli.so
(gdb) bt

At first glance, I see only one line in the function in ww8par6.cxx that might
cause an arithmetic exception, namely line 311:
aGrid.SetLines(writer_cast<sal_uInt16>(nTextareaHeight/nLinePitch));
Might nLinePitch being 0 be the problem?
