Created attachment 331620 [details] a sample screen output from described Description of problem: Here is a reliable way to bomb out from xpdf. - Start displaying some file - On a screen menu go to a full screen mode - Select with a mouse on a scree some rectangle - From a screen menu do "Zoom to selection" - Try to scroll up or down with "Page-Up" or "Page-Down" The last operation may, or may not, work for a moment but upon hitting a page boundary - kaboom! If cores are turned on then you may later find in there: Program terminated with signal 11, Segmentation fault. #0 0x000000335f87b4b2 in _int_malloc () from /lib64/libc.so.6 or Program terminated with signal 6, Aborted. #0 0x000000335f832f65 in raise () from /lib64/libc.so.6 It may be that some memory is somewhere stomped upon as core sizes and what is printed on a screen varies quite a bit. A fairly typical sample is attached. A sample trace from gdb (attached too) seems to show that in frame 6, XPDFCore.cc:82, the following code: XPDFCoreTile::~XPDFCoreTile() { if (image) { gfree(image->data); image->data = NULL; XDestroyImage(image); } } attempts to run gfree with image->data already NULL. Why this really happens, and if there are simpler ways than described to get similar effects, I have no idea. Version-Release number of selected component (if applicable): xpdf-3.02-9.fc11 xpdf-3.02-7.fc10 How reproducible: always as described Additional info: I tried that on rawhide and F10, x86_64 and i386 installations. It "works" every time.

Upstream confirms that they have this fixed in their next release, but isn't sure what change they made that fixed it, nor do they know when the next release will come out, so this one is going to go stagnant waiting on upstream to release again.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

The current xpdf-3.02-16.fc14, and surely xpdf-3.02-16.fc15 too, is crashing the same way as before. Even a backtrace from glibc with an invalid pointer did not change that much if at all. I wonder if this will ever get fixed.
Revisiting this issue. 3.03 seems to resolve this crash. Please test when the update hits.

Indeed that crash is gone (and I was rather worried that related troubles will resurface in more "everyday" scenarios but scrolling through a document in a big zoom and a full screen mode does have its uses). Thanks. xpdf-3.03 has quite impressive a version specific "laundry list" in CHANGES file. :-) Just a note: EPEL repos can benefit from these updates too. I did not notice anything new for EPEL on koji.
