ASAN suppressions don't work on an android application

[rbolgov]

There is a crash on android NDK application while AddressSanitizer processing on android x86 emulator. The asan stack trace points to GLES library as a crash reason. Unfortunately, no any possibility to skip the issue via suppressions options. The log shows the suppressions have been read but they don't work.

AddressSanitizer: reading suppressions file at /sdcard/asan.supp
==3512==AddressSanitizer Init done

halt_on_error feature doesn't work as well. I do able to change the asan options by /sdcard/asan.options (the option "redzone" is changeable as I see in the log)

1. Asan was installed on android emulator through the call from Mac machine:
~/Library/Android/ndk/toolchains/llvm/prebuilt/darwin-x86_64/bin/asan_device_setup --lib ~/Library/Android/ndk/toolchains/llvm/prebuilt/darwin-x86_64/lib64/clang/5.0.300080/lib/linux/libclang_rt.asan-i686-android.so --extra-options fast_unwind_on_malloc=0,include_if_exists=/sdcard/asan.options

2. asan.options and asan.supp files have been pushed to android
/sdcard/asan.options
suppressions=/sdcard/asan.supp
verbosity=2
print_suppressions=true
halt_on_error=0
/sdcard/asan.supp
interceptor_via_lib:libGLESv2_enc
interceptor_via_lib:libGLESv2_emulation
interceptor_via_lib:libGLESv2_enc.so
interceptor_via_lib:libGLESv2_emulation.so
interceptor_via_fun:glShaderSource
interceptor_via_fun:s_glShaderSource

3. Emulator info
Nexus 6
Android 6.0 x86 Marshmallow

4. clang version
~/Library/Android/ndk/toolchains/llvm/prebuilt/darwin-x86_64/bin/clang++ --version
Android clang version 5.0.300080 (based on LLVM 5.0.300080)
Target: x86_64-apple-darwin16.7.0
Thread model: posix

5. The native library was build via cmake as follows:
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-omit-frame-pointer -fsanitize=address -fsanitize-recover=address -fPIC")
set (CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} -fno-omit-frame-pointer -fsanitize=address")

6. Stacktraces

Any update on this issue?

I'm not sure what's going wrong. Try a newer build of NDK, try adding halt_on_error=0 directly to --extra-options. Try adding "debug=1" to the option, it might print something useful. Thank you for the very detailed report, btw. This part shows that halt_on_error_=0 somehow did not apply: #5 pc 000a5322 /system/lib/libclang_rt.asan-i686-android.so (__sanitizer::Die()+130) #6 pc 00088f95 /system/lib/libclang_rt.asan-i686-android.so (__asan::ScopedInErrorReport::~ScopedInErrorReport()+341) Errors from interceptors pass fatal==false here: explicit ScopedInErrorReport(bool fatal = false) : halt_on_error_(fatal || flags()->halt_on_error) {
