undefined symbol: __asan_option_detect_stack_use_after_return

I'm trying to compile C++ using clang's address sanitizer to output the sanitize results within a core dump, so I added:

CXXFLAGS += -fsanitize=address

to have the compiler options:

/opt/llvm-3.8.0/bin/clang++ \
  --gcc-toolchain=/opt/gcc-5.2.0 -fsanitize=address -DLINUX \
  -DLINUX64 -DTB_USE_RCU -DURCU_INLINE_SMALL_FUNCTIONS \
  -DU_USING_ICU_NAMESPACE=0 -DNDEBUG -D_POSIX_PTHREAD_SEMANTICS \
  -fPIC -D_GNU_SOURCE -DTB_USE_RCU -DTB_USE_RCU \
  -D_GLIBCXX_USE_CXX11_ABI=0 -m64 --gcc-toolchain=/opt/gcc-5.2.0 \
  -flto=full -std=gnu++14 -D_GLIBCXX_DEPRECATED= -pipe \
  -fno-omit-frame-pointer -ffast-math -fno-finite-math-only \
  -pthread -march=core2 -mtune=corei7 -g -O3 -Qunused-arguments \
  -fnon-call-exceptions -fvisibility=hidden \
  -fvisibility-inlines-hidden -Wall -Wextra -Wshadow \
  -Wpointer-arith -Wno-self-assign -Wno-unused-function \
  -Wno-gnu-empty-initializer -Wno-unused-parameter \
  -Wno-ignored-qualifiers -Wno-mismatched-tags \
  -Wno-unused-local-typedef -Wno-parentheses-equality \
  -Wno-unused-private-field -Wno-missing-field-initializers \
  -Wno-missing-braces -Werror=return-type \
  -Werror=overloaded-virtual -c MyClass.cpp -o MyClass.o

but I get the error:

undefined symbol: __asan_option_detect_stack_use_after_return

What's the simplest way to resolve this?

The executable need to link against the static ASAN library, should be done by, looks like you are using ld rather than clang for linking job. Check here.

-fsanitize=address -static-libasan

If you use cmake, it will be look like:

CXXFLAGS += -fsanitize=address -static-libasan
LDFLAGS += -fsanitize=address -static-libasan
