What does "Dwarf Error: Cannot find type of die" mean?

[Duncan Sands]

I sometimes see this kind of mysterious message in gdb when debugging code
compiled with gcc from CVS head.  Does anyone know what it could mean?

Die: DW_TAG_subrange_type (abbrev = 5, offset = 11562)
        has children: FALSE
        attributes:
                DW_AT_name (DW_FORM_string) string: "system__tasking__task_entry_index___XDLU_0__2147483647"
                DW_AT_lower_bound (DW_FORM_data1) constant: 0
                DW_AT_upper_bound (DW_FORM_data4) constant: 2147483647
                DW_AT_type (DW_FORM_ref4) constant: 1046
Dwarf Error: Cannot find type of die [in module /home/duncan/tmp/dbg2]

Thanks,

Duncan.

Hi Duncan,

Are you using the most up-to-date version of gdb?

I have gdb from cvs a few months ago (I moved to cvs because of
getting this error with earlier versions, but it didn't help).  Do you
think that isn't recent enough?

Thanks,

Duncan.

Hi Duncan,

GDB 6.0 (came out 2003.Oct.03) should be recent enough.

The real problem was that DW_TAG_subrange_type was not supported.
It is supported in current CVS, so all is well (so far)!

All the best,

Duncan.
