[Valgrind-users] Duplicate symbol ___eprintf in libclang_rt.eprintf.a and libclang_rt.osx.a

[Jim <jps...@gm...>]

I'm trying to compile valgrind SVN version 15929 using clang 3.8.1 on
target x86_64-apple-darwin15.6.0. I'm running on OSX 15.6 (El Capitan).
When tries to link vgpreload_core-x86-darwin.so, it fails with an error
regarding duplicate ___eprintf symbols.

Anyone see this before? I'm trying to figure out if this is an issue with
my system, or with the valgrind source. Note that I also tried compiling
the valgrind-3.11 stable release, but hit the same issue.

Error:
