Downstream is using dwz to de-duplicate DWARF data. dwz multifile mode factors out common debugging information into another file, and replaces the factored out data with references to the common file.
These references are represented as DW_FORM_GNU_strp_alt / DW_FORM_GNU_ref_alt, which apparantly causes problems with wine DWARF parser.
Is this use case supported?
I don't think there's any reason it shouldn't be supported, but currently Wine's DWARF parser doesn't really support anything higher than DWARF-2.
