Description

It looks like this might be due to a gcc bug since the failing code looks too simple to fail. The forwarding feature of objective C has been changed and raidem needs to adjust. From ticket 787396: Jakub Jelinek 2012-02-06 08:04:13 CST I guess this is related to http://gcc.gnu.org/ml/gcc-patches/2011-06/msg00254.html The segfault is because: 901 /* First try if the object understands forward::. */ 902 if (! frwd_sel) 903 frwd_sel = sel_get_any_uid ("forward::"); 904 905 if (__objc_responds_to (object, frwd_sel)) in __objc_forward has frwd_sel NULL when calling __objc_responds_to, supposedly because -forward:: has been removed from Object.m. Please talk to Nicola Pero on how you should adjust your code. I got some understanding of this today. The Token class needs to implement alloc and free at a minimum rather than trying to let Object handle them. Object doesn't provide much and forwarding has been removed, so we can't just pass stuff off. However, even though raidem is building with the changes, it is still segfaulting, though it seems a bit later on. Getting diagnostics right now is tough as the ptrace changes for selinux are a bit rough and seem to be causing an issue. There are definitely more classes with the same issue as Token. These all need to get fixed. Note this also affects F17 now that the branch has happened. I am currently trying yo fix this issue by using NSObject from gnustep-base as the base class instead of Object. Things are still crashing very early, but I have been addressing most of the compiler warnings. I still have a bit of work to do to replace all of the deprecated features that were dropped in gcc 4.7. Work is still needed, but I was able to get the start page to display. So I think this approach will work. I had this working but messed up getting my changes commited as a patch so I have a bit more grunt work to do. An update should be out in a day or two. raidem-0.3.1-20.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/raidem-0.3.1-20.fc17 Package raidem-0.3.1-20.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing raidem-0.3.1-20.fc17' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2012-2280/raidem-0.3.1-20.fc17 then log in and leave karma (feedback). raidem-0.3.1-20.fc17 has been pushed to the Fedora 17 stable repository. If problems still persist, please make note of it in this bug report. |
