Wireshark · Wireshark-users: [Wireshark-users] Debugging Wireshark dissector plugins

[sean bzd <seanbzd@xxxxxxxxx>]

I asked a similar question before but got no response. Can someone please provide some direction?

Problem:

I have a custom dissector and works fine most of the time; but sometimes, when I load the network capture containing packets (that the dissector is supposed to understand), the Wireshark application just hangs. The CPU consumption goes to 50% and stays there...it is as if it is in a tight loop. I'm using version 1.2.2 but same happens with different versions of wireshark; I know that the problem is in the dissector because if I remove the dissector plugin, wireshark is able to load the capture file. But i need some direction on how to proceed forward. Can i put some printfs in the dissector or elsewhere? Any other ideas?

Thanks,
Sean
