Ethereal-dev: Re: [Ethereal-dev] bug report : ethereal 0.10.10 crash for gsm mapmessage dump -
I checked in a fix for the SCTP problem in the file map.dump sent to
the list earlier.
Best regards

Hi,
When I open the trace with a build from current SVN I get [malformed
packet]
from
The SCTP dissector(wrong chunk length in the packet?) , using an older
SCTP
version I get the crash (fixed by the patch),
Thanks for the vote of confidence Tim :) I'll take a look at the ASN.1
coding when I have the time,
I suspect a newer version of the protocol is used than what's
currently in
the asn.1 file.
Best regards

Small fix to packet-ber.c to clear this crash, but there still might be
something wrong with the gsmmap checkiemi definition.

Im sure Anders has this in hand though.
