I have found the lookup by build-id (when lookup by /usr/lib/debug/path/name/exec.debug failed) does not work as LLDB tries the build-id hex string in uppercase but Fedora uses lowercase. xubuntu-16.10 also uses lowercase during my test: /usr/lib/debug/.build-id/6c/61f3566329f43d03f812ae7057e9e7391b5ff6.debug Differential revision: https://reviews.llvm.org/D42852 llvm-svn: 324222
