--- Comment #2 from Tony Josi <tonyjosinew at gmail dot com> --- In that case I think the warning should be generated for all the fields in the struct, why just the first 2 fields (ch1 and ch2 in the example struct in the bug report)? Also the warning is listed under [-Wattributes], as it is triggered only if -Wpacked is added, I would expect it to be listed with [-Wpacked]. It might be also a good idea to modify the help/man page of the -Wpacked to include about this warning if its a valid one, because currently the documentation of -Wpacked only talks about effects on struct layout. Thanks
