> Crashes were reported for 64 bit VMs on OSX running in "compressed oops with base" mode. The crash is caused by a SIGBUS on a correctly aligned access to the first page of the heap which is used for implicit null checks. With this change hotspot on OSX expects either a SIGBUS or SIGSEGV for implicit null checks.
