Hi Beth,

Things have been tightened up to prevent crashes from happening. Seems that your dissector does something it shouldn't.

Get out your debugger and see what it tells you.

Thanks,
Jaap

I wrote some plugins under 1.2.x awhile back, which have been used successfully for some time now.  

I tried using them with 1.4.0 (hey it was worth a shot :) but got an error so I downloaded the 1.4.0 tarball and rebuilt them.  However I still get the error!  Can those of you with 1.4 knowledge suggest where I should start looking for the problem?  The error is simply:
10:39:15          Warn Dissector bug, protocol MyProto, in packet 1: STATUS_ACCESS_VIOLATION: dissector accessed an invalid memory address
Whatever it is, it's something that happens with 1.4.0 but not with 1.2.11 .  I have not (yet) touched the plugin source code.
Any suggestions appreciated!
