    Description

      ADDITIONAL SYSTEM INFORMATION :
      # JRE version: OpenJDK Runtime Environment (8.0_392) (build 1.8.0_392-internal-fastdebug--b00) # Java VM: OpenJDK 64-Bit Server VM (25.392-b00-fastdebug compiled mode linux-amd64 compressed oops)

      A DESCRIPTION OF THE PROBLEM :
      I ran a modified regression test case on JDK8u392 and found that the JVM crashed with -Xcomp options.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      java -Xcomp -cp "6/" compiler.regalloc.TestC1OverlappingRegisterHint

      ACTUAL -
      Intervals 412 and 434 overlap and have the same register assigned
      412 int "[stack:3|I]" 209 209 [375, 440[ [446, 478[ 398 S 440 S 478 S "no optimization"

      434 int "[stack:3|I]" 238 238 [399, 404[ "no optimization"

      # To suppress the following error report, specify this argument
      # after -XX: or in .hotspotrc: SuppressErrorAt=/c1_LinearScan.cpp:3253
