Wireshark · Wireshark-dev: [Wireshark-dev] Possible bug with check_col?

[Brian Vandenberg <phantal@xxxxxxxxx>]

 I'm writing a dissector that relies on the http dissector.  The 
server's I'll be monitoring use ssl, so there's a requirement to use the 
ssl dissector to decrypt the packets and hand them off to the http 
dissector.

 Requests & responses are both treated properly during dissection, so 
that isn't an issue.  That is, with one caveat:  for some reason, the 
following code never causes the columns to be changed in my dissector, 
and it also seems to fail to do the same thing in the http dissector:

if (check_col (pinfo->cinfo, COL_PROTOCOL))
 col_set_str (pinfo->cinfo, COL_PROTOCOL, "ABBRV");

if (check_col (pinfo->cinfo, COL_INFO))
 col_set_str (pinfo->cinfo, COL_INFO, "Some info");

 The columns continue to say:

Protocol: TLSv1
Info: [SSL segment of a reassembled PDU]

 So, three questions: has anyone else seen this before, is this a bug, 
and is there a workaround?
