      Description

        (synopsis is provisional, feel free to change it or close as duplicate of known bug)

        Attached Fuzzer test fails like this:

        $ ./build/linux-x86_64-server-fastdebug/images/jdk/bin/java -XX:+StressIGVN -XX:StressSeed=77325781 -Xcomp -XX:CompileOnly=Test Test
        ...
        # Internal Error (/home/shade/trunks/jdk/src/hotspot/share/opto/phaseX.cpp:945), pid=2711484, tid=2711497
        # assert(no_dead_loop) failed: dead loop detected

        Bisection shows it started with JDK-8273612, but that might only be because the profiling info had changed a bit.
