Description
I am using wrap.sh script method to enable ASAN on my Android App, however I am not seeing any backtrace for a crash.
My Wrap.sh Script :
#!/system/bin/sh
HERE="$(cd "$(dirname "$0")" && pwd)"
export ASAN_OPTIONS=log_to_syslog=false,allow_user_segv_handler=1
export ASAN_OPTIONS="$ASAN_OPTIONS:verbosity=1:debug=1"
export LD_PRELOAD="$HERE/libclang_rt.asan-android.so $HERE/libc++_shared.so"
exec "$@"
Compiler flags:
_ASAN_COMPILER_FLAGS = [
"-g",
"-O1",
"-fno-omit-frame-pointer",
"-fsanitize=address",
"-fsanitize-address-use-after-scope",
"-Wno-unknown-sanitizers",
Pixel 2 device
App is 32 bit.
It works perfectly on x86_64 emulator, Problem is only with real Devices.
NDK : 15
Clang 7
Tried ASAN lib from pixel device and NDK 18 too
