Jungsoo Son:

AddressSanitizer of Gcc-4.8 is not available on Arm arch yet. I have found
it in gcc-4.8 release note.

[...]

Is there any way to test AddressSanitizer on arm through changing compile
option or enable some-feature?

Well, if it is not implemented, it is not implemented. There is nooption to change that.

However, GCC 4.9 will get ARM support for the address sanitizer. Itseems as if the following patch has been committed two weeks ago:http://gcc.gnu.org/ml/gcc-patches/2013-05/msg00338.html

Thus, you just need to build GCC 4.9 - and then -fsanitize=addressshould work.
