We'll need more info. What exactly are you doing, and what is the mapping the shadow conflicts with?

I try to build a empty project,it also report the error message.In my Android.mk, I have set
LOCAL_CFLAGS := -fsanitize=address
LOCAL_LDFLAGS := -fsanitize=address
LOCAL_ARM_MODE := arm

At the same time,In my Application.mk,I have set
APP_STL :=gnustl_static
NDK_TOOLCHAIN_VERSION=clang3.5

The NDK version is r10d or r10e

Surely,many android devices can not start as root. The script of asan_device_setup can not run successfully!
So,I copy the libclang_rt.asan-arm-android.so to /system/lib/ by my self. At the same time, I have set the envionment variables as follow:
export LD_PRELOAD="/system/lib/libclang_rt.asan-arm-android.so"
export ASAN_OPTIONS="start_deactivated=1,alloc_dealloc_mismatch=1"

Is there anything else to do?

These variables need to be set in the Zygote process, not in "adb shell" environment. I think this is reason that it report the "Shadow memory ..." error message. When I try to run the script of asan_device_setup,it reports the message as follow:

Additionally,I run the script of asan_device_setup successfully in Mi3 and Mi4. But Both the android devices can not restart successfully! After run the script successfully, the android devives break down!
I fell very sad about it ...

I think it is the reason that the android devices can not restart successfully!
I believe in that you can resolved it by the logcat!

In another android device that run the script successfully, it also can not restart again. The log msssage is follow:

Surely,the first crash is reported in Android4.x,but the second crash is reported in Android6.0.1.
I do not know what can I do for this.
Do you have any suggestions about the second log:
06-29 11:36:31.921 15094 15094 I : #1 0xb6a187e7 (/system/lib/libclang_rt.asan-arm-android.so+0x6c7e7)

It is reported in Android 6.0.1.

@woxinchangdanzou Hi, I meet the same problem on LGE Nexsus 5(Android 6.0.1), did you solve it after running the asan_device_setup? But when I run it, I get some errors:

How did you solve this, please help me, thanks.

Hey, in the process map collected
06-27 20:32:02.712 26402 26402 I : ==26402==Process memory map follows:

What does the (deleted) keyword mean?
