--- Comment #2 from Mark Wielaard <mark at klomp dot org> ---
This is slightly tricky, because I think we technically do the right thing
here.
dwfl_module_return_value_location returns that cannot handle DWARF type
description error, which is technically correct, since it is an
unspecified_type.
dwfl_module_return_value_location can return an error (< 0) which means either
bad DWARF or unknown/unhandled type, it can return zero, which means the
function has no return value, or it return the number of DWARF expression
operations (> 0) that describe how to get the value returned by the function.
Sadly we don't have an easy way to distinguish between bad DWARF/type and
cannot handle type.
I think we can change the testcase though, to check for the special case of
DW_TAG_unspecified_type.
