readelf -w dumps most of it.  It's a bit low level to understand
easily, though.

Similar errors from GDB mean that it needs to be patched to recognize
DW_FORM_strp.  Whichever program is printing this stuff (addr2line?)
presumably needs a similar patch.

There's something else happening which triggers this stuff, but I
wouldn't know what that is.
