Hi All,
I am very new to Address Sanitizer. I implemented Address sanitizer on
sample c/c++ files named "free.c" and got error reports in command
terminal. Command I used for the same , I am mentioning below:
*clang -fsanitize=address -O1 -fno-omit-frame-pointer -g
tests/use-after-free.c*
output: Ex-1
% ./a.out

SUMMARY: AddressSanitizer: heap-use-after-free use-after-free.c:5 main
Likewise , I want to implement Address Sanitizer on AOSP c/c++ files while
building the source code. I want similar kind of error reporting in
building AOSP with Address Sanitizer.
I tried adding some *CFLAGS and LOCAL_SANITIZE tags in Android.mk* files
and kept the same sample "free.c" files in an apps folder. It is getting
build successfully but it should give same error report as it is throwing in
Ex-1 above.
If anyone knows, please help me on this. Thanks in advance.
Thanks and regards,
Anupam Anurag
