It seems the issue is caused by libtool. clang refers to libclang_rt.asan_osx_dynamic.dylib automatically if -fsanitize=address flag has been passed. However, libtool-2.4.6 drops the flag[1][2].
The last commit of libtool adds support for the flag[3]. I modified libtool.sh in my TS build tree, and it works (with -no-undefined flag). So, a workaround is, as described in the FAQ, put the flag in CC and CXX when you run configure. CC="clang -fsanitize=address" CXX="clang++ -fsanitize=address" CXXFLAGS="-Werror -fsanitize=address" CFLAGS="-Werror -fsanitize=address" LDFLAGS="-fsanitize=address" ./configure --disable-luajit [1] https://lists.gnu.org/archive/html/libtool/2014-04/msg00026.html [2] http://www.gnu.org/software/libtool/manual/libtool.html#Stripped-link-flags [3] http://git.savannah.gnu.org/cgit/libtool.git/commit/?id=a5c6466528c060cc4660ad0319c00740db0e42ba On Wed, Jan 13, 2016 at 9:32 PM, Masakazu Kitajo <m4s...@gmail.com> wrote: > Thank you all. > > I tried Bryan's command line, but I'm still not able to build with > -no-undefined flag. -static-libasan flag doesn't work too. > > I'm going to dig a little deeper.
