RE: Bad struct name in gdb with g++ 4.1.2

readelf -wi gives me the following

[...]
<1><66>: Abbrev Number: 2 (DW_TAG_structure_type)
DW_AT_sibling : <8e>
DW_AT_name : ._0
DW_AT_byte_size : 8
DW_AT_decl_file : 3
DW_AT_decl_line : 1
[...]

This is a compiler bug then.

Thanks,

Michel

I would suggest looking at the debuginfo.
You can do this with "readelf -wi".
If that shows the strange names, then it is a compiler bug.
