To me it looks like a build error in the clang++ asan support shared librar= y: If libclang_rt.asan-x86_64.so uses the symbol pthread_attr_get_np then it should be linked against the shared library that provides that symbol. But if this is not possible for some reason then changing the driver to link against libpthreads when using the shared library version of asan seems bet= ter to me. --=20 You are receiving this mail because: You are the assignee for the bug.=
