  To reproduce checkout the latest state of the IR Framework (https://github.com/chhagedorn/valhalla/tree/TestingFramework)
  and run compiler/valhalla/inlinetypes/TestIntrinsics.java with "-XX:+UnlockExperimentalVMOptions -XX:+DeoptimizeALot"
Comments
The similar failure is observed by running compiler/valhalla/inlinetypes/TestBufferTearing.java (old framework based test) # Internal Error (/opt/mach5/mesos/work_dir/slaves/3c846bae-ce30-4a97-93ee-9fef4497ccb6-S79388/frameworks/1735e8a2-a1db-478c-8104-60c8b0af87dd-0196/executors/eb9e94db-f0ec-4c3e-8ffe-7aeffb334b4a/runs/8d3599f2-f73a-41b1-ba0a-3ae4dee93ea1/workspace/open/src/hotspot/share/prims/unsafe.cpp:241), pid=26019, tid=26064 # assert(!_obj->is_inline_type() || _obj->mark().is_larval_state()) failed: must be an object instance or a larval inline type
