> # Internal Error (/export/users2/lab_ipfjbld/nightly/dev/r1767_08-12-22_0800/sources/hotspot/src/share/vm/opto/memnode.cpp:3793), pid=5400, tid=2305843017755292288

The reason of failure is that the assert happens because during iGVN optimization after macro expanding the base
memory of MergeMem node does not satisfy the assertion. This MergeMem node is located between AllocateArray and Initialize nodes.
