[cfe-dev] Building with ASan giving 'undefined ___asan_init_v4'

[Alexey Samsonov]

You should update (rebuild from trunk) the ASan runtime you use (IIRC it's
a dylib on Mac). We occasionally bump the version of __asan_init to mark
the ABI changes (changes in the interface between compiler instrumentation
and runtime library).
