        Description

        Starting from JDK8-b107 / hs25-b49 JVM crashes with assert "assert(is_updated()) failed: must not be clear" with -XX:+PrintGCApplicationConcurrentTime in -Xcomp mode:

        jdk1.8.0-b110/fastdebug/bin/java -server -Xcomp -XX:+PrintGCApplicationConcurrentTime Test
        # To suppress the following error report, specify this argument
        # after -XX: or in .hotspotrc: SuppressErrorAt=/timer.cpp:94
        #
        # A fatal error has been detected by the Java Runtime Environment:
        #
        # Internal Error (/HUDSON/workspace/8-2-build-linux-amd64/jdk8/367/hotspot/src/share/vm/runtime/timer.cpp:94), pid=27643, tid=139688482621184
        # assert(is_updated()) failed: must not be clear
        #
        # JRE version: Java(TM) SE Runtime Environment (8.0-b110) (build 1.8.0-ea-fastdebug-b110)
        # Java VM: Java HotSpot(TM) 64-Bit Server VM (25.0-b52-fastdebug compiled mode linux-amd64 compressed oops)
        # Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again
        #
        # An error report file with more information is saved as:
        # /tmp/hs_err_pid27643.log

        Issue could be reproduced with -XX:+PrintGCApplicationConcurrentTime, but not with -XX:+PrintGCApplicationStoppedTime.
        I was able to reproduce it only in -Xcomp mode with both C1 and C2, but with -Xint and -Xmixed nothing happens.
