Wireshark · Ethereal-dev: RE: [Ethereal-dev] bug report : ethereal 0.10.10 crash for gsm mapmessage dump

["Tim" <tim@xxxxxxxxxxxxxxx>]

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.

Hi,
