We're seeying these errors with GCC and Clang on different systems, while some other identical OSs on different boards fail. Like many other ASAN tests, there seem to be no easy way to investigate this other than someone familiar with the sanitizer code and the ARM libraries. At least, for now, we'll silence the bots. I'll create a bugzilla entry. llvm-svn: 287464
