The test java/util/TimeZone/OldIDMappingTest.sh fails in the compiler nightlies of 2016-03-28 due to an EXCEPTION_ACCESS_VIOLATION in the C1 compiler. Unfortunately, no stack trace is available. The failure happens while compiling the following method:

Current CompileTask:
C1: 517 257 3 jdk.internal.org.objectweb.asm.Frame::execute (2252 bytes)

The hs-comp repository was synced to hs last Thursday, but the failure does not appear in any other repository. The following C1-related changes in hs-comp have not made it into hs yet: JDK-8151818, JDK-8152698 and JDK-8148175. JDK-8149644 touches the compiler interface, so that might cause this failure as well.

It is likely that we can exclude JDK-8148175 as a cause because its changes do not affect code that is called at compilation time. JDK-8152698 removes intrinsics, so that is likely to have not caused the problem either. But more investigation is necessary.
