Note: to actually generate backtrace, modifying llvm.spec was needed (bug 982075).

You can reproduce this with:
* $ fedpkg co xscreensaver
* (and use master branch)
* Change "use_clang_analyze 0" to "use_clang_analyze 1" in xscreensaver.spec
* $ fedpkg local

Reassign to nobody@.  I have no time and no interest in working on clang, and the only reason it's even in the llvm package is because it can't be built any other way.

If anyone wishes to volunteer for comaintainer with a focus on clang, please let me know (preferably with direct email, if it's in bz I'll likely miss the request), I'll be happy to hook you up.
Comment 14 Jan Včelák 2014-12-26 00:08:21 UTC 
Unable to reproduce with clang-3.4-10.fc20.x86_64. Seems to be resolved during some rebase.
