Description Olivier Fourdan 2010-06-02 11:51:33 UTC
Description of problem:

When browsing a given PDF file, evince exits with a "Bogus memory allocation size" error

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Open the PDF file in evince
2. Page down to page 13 / 15
Actual results:

evince exits with "Bogus memory allocation size"

Expected results:

evince does not exit

Additional info:

The problem does not occur in recent version of Evince. There is also an error displayed "Dictionary key must be a name object" but that's unrelated to the bogus memory allocation.

The message "Bogus memory allocation size" can come from different part of the code.

So breaking on _exit() in gdb, we can get a clearer idea of the code path that leads to the error:

The values of a, b and c are optimized out, so gdb won't be of much help here.

Instrumenting poppler lib, we can get thr values actually passed to gmallocn3(), it's :

   a=1, b=0, c=72

So the program exits because b=0 

In poppler/, current upstream uses:

   subband->cbs = (JPXCodeBlock *)gmallocn(subband->nXCBs *

Instead of

   subband->cbs = (JPXCodeBlock *)gmallocn3( subband->nXCBs,

So that if subband->nYCBs == 0, subband->nXCBs * subband->nYCBs == 0 and the problem does not occur.

Patch for poppler 0.5.4 attached.
