(Whiteboard: GCC ASan needs at least v4.8.x for x86/64-bit support, v4.9.x for ARM support) 

It will be nice to be able to explore having Firefox OS ASan builds, to find security issues.

:decoder mentioned that MSan & Desktop Firefox is not likely to happen, much less for Firefox OS, so updating summary to reflect that.

We dug further and found that GCC ASan needs at least v4.8.x for x86/64-bit support, v4.9.x for ARM support, unless we use Clang.

There was work to explore building b2g with LLVM. We successfully build b2g-info with ASAN, but it fails to build gecko. The LLVM parser crashed in building a test program generated by the configure script. We might give gcc-4.9 another try.
