Control: tag -1 - patch + moreinfo After looking into this some more, I don't think this is necessarily a bug in dwz, but it could also be either someone using rogue DW_OP_* definitions with values 0x00 and 0x01 or a buggy compiler/assembler backend emitting junk. While applying the patch probably won't hurt, it will most probably not help either.
@Diego: Could you still provide us with the unstripped shared library? That would make tracking this down much easier. Regards, Dennis
