Subject: [Bug libdw/23981] dwarf_siblingof() fails with attribute form DW_FORM_ref_addr

--- Comment #3 from Andreas Kromke <Andreas.Kromke at dreamchip dot de> ---
I changed the source file accordingly, rebuilt the library and rerun the tests.
The result is, unfortunately, the same, i.e. there is no improvement.
Analysis showed that in failure case these lines are executed:
if (sibattr.form == DW_FORM_ref_addr)
and
uint8_t ref_size;
and
ref_size = cu->address_size;
and
__libdw_seterrno (DWARF_E_INVALID_DWARF);
return -1;
So obviously the new code piece was run, but the failure was still detected
later, in the old code.
