from Guy Harris
To quote an email to the wireshark-dev list:
> I am having problems with saving my new development as a pcapng file. Trying to save with this type, wireshark 2.1.0 (x64) crashes and I will get an exception.
> Using the VS2013 debugger I get the following exception within “pcapng.c”:
Unhandled exception at 0x000007FEE02F7C67 (wiretap-2.1.0(x64_TS_PS).dll) in
Wireshark.exe: 0xC0000005: Access violation reading location
0x0000000000000000.
> The programm itself seems to stop at line 4031 in “pcapng.c”
if (!pcapng_write_interface_statistics_block(wdh, if_stats, err)) {
return FALSE;
}
> What I don’t understand is, trying to save another capture with the same development as pcap works perfect. I can also load the pcap file without any problems. After saving the file as pcap I tried to save the same capture as pcapng, and it works! Due to the fact that I am able to save a capture with my new development as pcap I can’t believe, that my development is responsible for this crash?
Perhaps the code that *reads* pcapng files is setting up the statistics
incorrectly, setting int_data_mand->num_stat_entries to 1 and not actually
setting up an array with one element?
