Hi Pascal,
It seems that libsmi 0.4.8 is more picky than 0.4.7 I tested my patch with. :-( I plan to remove the workaround from Wireshark as it makes more problems than it solves. It means that https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=4174 will remain open. 

Any objections?

Cheers,
Balint

    I've committed a refinement to the workaround based on Vincent's email
    [1] in 32017.
It seems to be working fine on Linux but on Windows I still get a popup when launching wireshark or the following text when launching tshark (SVN revision 32067):
tshark: Stopped processing module SNMPv2-SMI due to error(s) to prevent potential crash in libsmi. 
Module's conformance level: 1.
See details at: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560325

Is it a known issue ? Can something be done for us poor Windows user ? ;)

Regards,
Pascal.
