how to solve the problem of Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING

[daliands]

I built addresssanitizer in aosp/5.1.1/external/compiler-rt/lib/asan,,then I found asanwrapper in /system/bin and libclang_rt.asan_arm_android.so in /system/lib.then i push libclang_rt.asan-arm-android.so in system/lib and push app_process in /system/bin/asan。Then I run my asan test apk,it has a shadow memory problem,Sorry for the bad English.

Q: I'm using dynamic ASan runtime and my program crashes at start with "Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly.".

A1: If you are using shared ASan DSO, try LD_PRELOAD'ing Asan runtime into your program.
A2: Otherwise you are probably hitting a known limitation of dynamic runtime. Libasan is initialized at the end of program startup so if some preceeding library initializer did lots of memory allocations memory region required for ASan shadow memory could be occupied by unrelated mappings.

Thank you, @chefmax I have tested LD_PRELOAD at first. but the rom can not start .i will check it later. @yugr I build the rom with make USE_CLANG_PLATFORM_BUILD:=true SANITIZE_TARGET=address -j42,but it does not change anything .
