I am trying to build a simple Android binary to test out UBSAN (Undefined behavior sanitizer) using ndk r15c and clang. However the build fails when trying to link with the following error:
jni/main.cpp:17: error: undefined reference to '__ubsan_handle_type_mismatch_v1'

My Android.mk file is as follows:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_CFLAGS += -Wall
LOCAL_LDLIBS := -L$(LOCAL_PATH)/lib -llog -g
LOCAL_C_INCLUDES := bionic
LOCAL_C_INCLUDES += $(LOCAL_PATH)/include
LOCAL_SRC_FILES:= main.cpp
LOCAL_CPPFLAGS := -Wall -fPIE -fexceptions -fsanitize=undefined
LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog -fPIE -pie -fsanitize=undefined
LOCAL_MODULE := ubsan_test
include $(BUILD_EXECUTABLE)
My Application.mk is as follows:
NDK_TOOLCHAIN_VERSION:=clang
APP_STL:=stlport_static
APP_ABI := armeabi armeabi-v7a
APP_PLATFORM := android-17
I am guessing that I am missing some linker flag or some other setting but haven't been able to figure out what is going on. Looking at the symbols in the ubsan runtime, the sybols so seem to exist.
Note: I have also tried using LOCAL_SANITIZE := undefined instead of -fsanitize=undefined in my Android.mk with the same result.
