            Bug ID: 34286
           Summary: llvm-symbolizer-*** in LLVM package needs a symlink to
                    llvm-symbolizer so that clang can find it.
           Product: Packaging
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: deb packages
          Assignee: unassignedbugs at nondot.org

I was trying to use LSAN with a stock apt-get clang/llvm on 16.04. I was
surprised to discover that my suppressions list was not working. In the process
of investigating I discovered that while llvm-symbolizer-*** is installed
(where *** is the version number), no symlink is created from the enabled
llvm-symbolizer-*** to llvm-symbolizer. This causes LSAN to not be able to
symbolicate frames and thus limits the ability to suppress.

When I looked at the LLVM package's filelist:

https://packages.ubuntu.com/xenial/amd64/llvm/filelist

I noticed that llvm-symbolizer is not there. It really should either be added
there or clang should be taught how to use the llvm-symbolizer-*** that it
corresponds to. Otherwise, LSAN is not fully functional straight out of the box
(an anti-goal).
