    c_protocols = new PP_Var[protocol_count];
    if (!c_protocols)
      return PP_ERROR_NOMEMORY;
  }
  ....
}

This suspicious code was found in Chromium project by PVS-Studio static code analyzer.
Warning message is:
V668 There is no sense in testing the 'c_protocols' pointer against null, as the memory was allocated using the 'new' operator. The exception will be generated in the case of memory allocation error. websocket.cc 44
