What does mean? And must i do something about?
It means that dwz cannot handle the DWARF and that it doesn't compress
any of it. It isn't fatal. But it makes your debuginfo packages much
bigger than they need to be. Please file a bug report against the dwz
that it needs to handle DW_OP_GNU_variable_value (253/0xfd) which gcc
emits since GCC7.
Thanks,
