    Description

      This reproduces reliably with an internal test:

      # A fatal error has been detected by the Java Runtime Environment:
      #
      # Internal Error (workspace/open/src/hotspot/share/opto/parse1.cpp:180), pid=791450, tid=791463
      # assert(_gvn.type(l)->higher_equal(type)) failed: must constrain OSR typestate
      #
      # JRE version: Java(TM) SE Runtime Environment (20.0+25) (fastdebug build 20-ea+25-1866)
      # Java VM: Java HotSpot(TM) 64-Bit Server VM (fastdebug 20-ea+25-1866, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64)
