@delcypher, @yln maybe you can check if this works on iOS

@vitalybuka Sorry. I didn't see this before.

Unfortunately the CMake code doesn't generate an iOS testing configuration for the sanitizer_common tests currently. This is something we are thinking about enabling but just haven't had time to do.

However just to see what happened I moved the test into ASan's test directory and ran on an iOS device and in the iOS simulator (12.2 runtime). The test passed so this change LGTM.
