Description
compiler/types/correctness/OffTest.java crashes VM with SIGSEGV:
#
#  SIGSEGV (0xb) at pc=0x00007f86e078522b, pid=22727, tid=140216861116160
#
# JRE version: Java(TM) SE Runtime Environment (8.0-b132) (build 1.8.0-b132)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.0-b62-internal-fastdebug mixed mode linux-amd64 compressed oops)
# Problematic frame:
# V  [libjvm.so+0xcc622b]  MethodData::next_data(ProfileData*) const+0x1b
#

TypeProfiling is turned on with -XX:TypeProfileLevel=010

Test failed on the next test case:
hierarchies.DefaultMethodInterface$Hierarchy :: ArrayCopy # RETURN @ MethodHandleDelegate # execution.TypeConflict
This means that we executed return type profiling test that exercises System.arraycopy usage in the method invoked with MethodHandles.invoke.
