I would still suggest the asn1 change if we are doing a temporary fix, beca= use: - It does not add any new symbol versioning, it just converts the 'global: *' to an explicit list of symbols. - there are other libraries lined to asn1 which may have the same issue as libkafs5 (I haven't really looked at this. The only downside I see is that libasn1 has a lot of symbols. JC.
