-XX:+CheckMemoryInitialization seems to be broken. When running a Java program the VM crashes with:

# Internal Error (/oracle/hs/hotspot/src/share/vm/gc/shared/collectedHeap.cpp:257), pid=10632, tid=10633
# assert((*(intptr_t*) (addr + slot)) == ((intptr_t) badHeapWordVal)) failed: Found non badHeapWordValue in pre-allocation check
