test9() in scenario 0 of test

    compiler/valhalla/inlinetypes/TestLWorld.java

crashes intermittently.

It can be triggered more reliably when passing the following javaopts:

    -DScenarios=0 -DTest=test9 -DWarmup=2000 -XX:CompileCommand=repeatcompilation,*::test9,1000 -XX:-TieredCompilation -XX:+StressLoopPeeling
