[Android O Nexus 6P]==22003==Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING.

I follow this guide https://github.com/google/sanitizers/wiki/AddressSanitizerOnAndroidO to complete configuration of my project, copy the libclang_rt.asan-arm-android.so and wrap.sh to the native libraries directory. But when I run my app, it cannot run and I get these logs.

Device: Huawei Nexus 6P Os Version: 8.0 NDK: r10e

This is a kernel version that is incompatible with older versions of asan. Unfortunately, even the latest NDK does not have the fixed version of asan. The kernel patch has been reverted at some point, so a future update might fix it (or not).

You can grab a newer toolchain from chromium, but I'm not sure it will work as a drop-in replacement for NDK. Most likely not. http://commondatastorage.googleapis.com/chromium-browser-clang/Linux_x64/clang-325667-1.tgz

@eugenis Thanks, but do you mean it's not sure when the ndk team can fix this issue?

[eugenis]

LLVM fix is in r318666, eventually it will be included in the NDK. Not sure when.
