Debug assert triggered in test suite 5.4 win32

[Alex Budovski]

Hi, just running the test suite on windows I get a debug assert here:

Call stack:

 	mysqld.exe!_NMSG_WRITE(int rterrnum=10)  Line 198	C
 	mysqld.exe!abort()  Line 59 + 0x7 bytes	C

protocol.cc:415

  default:
    DBUG_ASSERT(0);  // <-- here.
    net_send_ok(thd, thd->server_status, thd->total_warn_count,
                0, 0, NULL);
    break;
  }

Is that expected?
