libvorbisfile for i686 always fails at ov_open_callbacks()
Last modified: 2013-02-13 03:23:50 EST
Created attachment 591804 [details] A small C program to demonstrate the bug. Description of problem: Basically, any attempt to load an Ogg Vorbis file will fail on Fedora 16 32-bit because it always tries to use SEEK_SET (or just 0, really) on the seek callback. Version-Release number of selected component (if applicable): 1.3.3-1 How reproducible: 100%. Multiple machines tested with both 32-bit and 64-bit installations of Fedora. Steps to Reproduce: See attachment for a quick demonstration. If you want to trace the issue above you can make your own callbacks that print the SEEK_??? value. Actual results: The best case is that you just get an OV_ENOTVORBIS error, but the worst case (the default one, actually) is that you're stuck in an infinite loop of attempting to call the seek function with a bad value. Expected results: ov_open_callbacks() loading the Vorbis data without errors. In the case of the attached example, just getting a return value of 0. Additional info: libvorbis for x86_64 seems to be fine. In fact, libvorbis.fc17.i686 seems to be fine as well, but I have not tested this myself.

Typos for: Description: It will fail on a 64-bit installation when you use the 32-bit lib. I've not tested it on 32-bit Fedora 16. Reproducible: It's been tested on multiple 64-bit installations, comparing both the 32-bit and 64-bit libs. I also ran the attachment on a virtual FC17-32 environment and it seemed to be happy there, but that's the only testing I've done on an x86 installation.
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '16'. 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 16'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 16 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, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. 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
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
