Well, the type is the interface: there's nothing else it might be. > I'd need a backtrace to be more specific, but in addition to bad > debug info this may be a limitation in GDB; it does not know > anything about DW_TAG_interface_type. OK, thanks. Anyway, on inspection it seems like read_type_die() in dwarf2read.c doesn't know how to handle DW_TAG_interface_type. This is rather odd, given that dwarf_tag_name() does know about interface types. Maybe I should just fix gcj not to use DW_TAG_interface_type.
