The reason behind this is that the capture file appears to be damaged or corrupt; that's why the error message says "The capture file appears to be damaged or corrupt." That error will not occur as a result of problems in packet dissector code unless that code overwrites some data structure for the Wiretap library. Did you build a separate version of Wireshark with your changes? Is the version without your code just a standard distribution, or is it something you built from the same source tree using the same build process as the version with your changes, so the only difference is your changes? If not, what happens if you back out your changes, rebuild Wireshark, and try reading that file with that version? On what operating system are you running Wireshark? What version are you running? Is the capture file gzipped? Where was the capture done? _______________________________________________ Wireshark-dev mailing list Wireshark-dev@wireshark.org http://www.wireshark.org/mailman/listinfo/wireshark-dev
