*** glibc detected *** double free or corruption (fasttop): 0x082a9ec8 ***

[David Sterratt]

I start up ooffice2 (or ooffice) with the attached document. It appears to load,
but then does not display, and openoffice hangs. I get the following error message:

~$ ooffice2 ~/text/teaching/mscns-dtc/passive-buggy-minimal.sxi
*** glibc detected *** double free or corruption (fasttop): 0x082a9ec8 ***

It looks like it might be related to this openoffice bug, which only seems to be
a problem on Debian or Ubuntu:

.sxi file that causes ooffice2 to crash

[David Sterratt (david-c-sterratt)]

Should have said: this file seems to cause no problems on Fedora Core 3 with
openoffice 1.1.3.

I'm encountering the same problem with the file that worked fine in Hoary (OOo
v1.1.5). After upgrade to Breezy the OOo 2 beta hangs with the "double free or
corruption (fasttop)". The same for OOo 1.1.5 in Breezy.

I've diagnosed the problem a bit and it looks like the problem is slide preview.
The OOo 1.1.5 works fine until a slide preview is displayed somewhere. As the
OOo 2 display a slide preview by default, it hangs right after startup.

This problem appears to be more general. I'm having OpenOffice 2.0 crash in
breezy whenever I load a document with a windows metafile graphic. The document
loads fine, but crashes as soon as it gets to the point where it should be
displaying the graphic. Not all wmf graphics crash OpenOffice, but at least one
does.

I'll add one more piece of information: I recently uninstalled all the Ubuntu
OpenOffice2 packages and installed the "official" rpm packages using alien. The
file and graphic that caused the Ubuntu OpenOffice2 to crash _do not_ cause a
crash when opened with the official OpenOffice2 packages running on Ubuntu. I'm
not sure what this means, but I thought I'd report it.

[Joachim Geiler (joachim-geiler)]

I had the same problems with OOo1.1.5, OOo2 ubuntu and the official OOo2.

The problem seems to be in glibc2:
If You set the environment variable MALLOC_CHECK_ to any value of 0, 1 or 2, the
error disappears. According man (3) malloc I think, with MALLOC_CHECK_ set to 2 a
double free() should be detected.

My workaround for now is to set this variable in the /usr/bin/openoffice scripts.

Although I could swear that everything worked fine after I installed the
official rpm's, when I went back to test today, the official distribution
seemed to show the same bug as the ubuntu package. Sorry about the noise.
