The source:
procedure AdaFF is
type rec is
record
null;
end record;
X : rec;
begin
null;
end AdaFF;
produces output by:
$ rm -f adaff{,.o,.ali};gnatmake -g adaff.adb ;readelf -a --debug-dump adaff |
grep 'DW_AT_byte_size.*0xffff'

A more complicated testcase

crashes GDB eating all the memory on `print x' there.
