We ourselves test only Android ARM on a real box. There the tests work. On ARM Linux there are quite a few known test failures (mostly due to unwinding), and no public regular testing. See e.g. http://reviews.llvm.org/D3857 We don't have any experience with running asan on quemu and I remember some complaints regarding quemu itself, e.g. https://code.google.com/p/address-sanitizer/issues/detail?id=160 As usual: if you are interested in supporting asan on any given platform, please work with us upstream. > > On a board where this
