*** Bug 957587 has been marked as a duplicate of this bug. *** Hi, Is there any progress on this bug? Are we going to ship a "broken" compiler again? :-( Update: Clang's ASAN feature is still broken in Fedora 19. Created attachment 768253 [details]
updated SPEC file
Hi Adam, I have attached an updated SPEC file to fix the problem. It now builds LLVM 3.3 release (instead of building pre-releases) and ASAN feature now works great. Please test and let me know how it goes. Seems that ASAN still missing in fedora 20 ... YC Created attachment 807045 [details]
newly updated SPEC file
Attached SPEC file seems to work. See http://koji.fedoraproject.org/koji/taskinfo?taskID=6019218 I would really love to see this working. Any update on this bug? (And other LLVM bugs? Just a few features provided by LLVM work in Fedora unfortunately.) When you compile clang from sources, everything is working fine (tested with the git repo). It's a little bit long to compile, but all the plugins works. I have submitted fixed (and tested!) .spec files multiple times already. I simply do not understand why it is taking so long (close to a year now!) to fix this trivial bug. Please allow someone else to maintain / co-maintain this package. I really don't want to use the "unresponsive maintainer" resolution path. I wrote to Adam a few days ago and we talked about it. I'm looking into this and several other LLVM bugs. I will try to help Adam to resolve this bug ASAP. *** Bug 1026101 has been marked as a duplicate of this bug. *** llvm-3.3-2.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/llvm-3.3-2.fc20 Package llvm-3.3-2.fc20: * should fix your issue, * was pushed to the Fedora 20 testing repository, * should be available at your local mirror within two days.

I'm not sure if update in F19 is safe enough. There were quite a lot of changes in the package. I want to be sure that I didn't break anything. llvm-3.3-2.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/llvm-3.3-2.fc19 llvm-3.3-3.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/llvm-3.3-3.fc19 llvm-3.3-2.fc20 has been pushed to the Fedora 20 stable repository.
