           Summary: dnsd not working on x86_64 systems
           Product: Busybox
           Version: 1.17.x
          Platform: All
        OS/Version: All
            Status: NEW

The positive anwsers from dnsd are not readable when dsnd is running on 64bits
systems.
This is due to line 391 of dnsd.c : "query_len +=
sizeof(unaligned_type_class);".
unaligned_type_class is a pointer and what we want here is the size of the
object. This object's size is 32bits this is why the problem only appears on 64
bits systems.
The solution is to change the line for : "query_len +=
sizeof(*unaligned_type_class);"

Best regards
