                    analyzer/constraint-manager.cc:581
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: ice-checking, ice-on-valid-code

g++-12.0.0-alpha20211003 snapshot (g:d91056851c5c60f226e3192fb955d018b53eb66f)
ICEs when compiling the following piece of C code w/ -fanalyzer -fstrict-enums:

enum OpCode {
  OP_MOVE,
  OP_LOADK,
  OP_LOADBOOL,
  OP_LOADNIL,
  OP_GETUPVAL,
  OP_SETUPVAL
};

enum OpArg {
  OpArgN,
  OpArgU,
  OpArgR,
  OpArgK
};

void
symbexec_lastpc (enum OpCode symbexec_lastpc_op, enum OpArg luaP_opmodes)
{
  switch (luaP_opmodes)
    {
    case OpArgN:
    case OpArgK:
      {
        switch (symbexec_lastpc_op)
          {
          case OP_LOADNIL:
          case OP_SETUPVAL:
            break;
          default:
            break;
          }
      }
    default:
      break;
    }
}
