      Description

        (synopsis is provisional, please change as you see fit)

        The attached Fuzzer test fails like this:

        $ ../build/linux-x86_64-server-fastdebug/images/jdk/bin/java -Xmx512m -Xcomp -XX:CompileOnly=Test -XX:TieredStopAtLevel=1 Test

        # A fatal error has been detected by the Java Runtime Environment:
        #
        # Internal Error (/home/shade/trunks/jdk/src/hotspot/share/c1/c1_LinearScan.cpp:858), pid=1577021, tid=1577034
        # assert(false) failed: live_in set of first block must be empty

        There is a superficially similar bug report with a similar assertion (JDK-8271202), but this one does not require deopt flags, and also the current patch from JDK-8271202 does *not* solve this failure.

        I also bisected it to JDK-8264066 (CPU) patch -- therefore I provisionally set all suspected affected versions:
