https://bugs.winehq.org/show_bug.cgi?id=45242 --- Comment #6 from Jinoh Kang <jinoh.kang.kr(a)gmail.com> --- 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? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

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. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

Which is to say, I think this is probably a valid bug, if not a trivial one to fix. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
