13418d4800 8025728: Missing volatile specifier for field G1AllocRegion::_alloc_region 
The field G1AllocRegion::_alloc_region needs to be declared volatile as it is used with that intention. Otherwise the compiler may generate the code that reloads the value which might have changed in the meantime, leading to spurious crashes.
