Wireshark · Ethereal-dev: [Ethereal-dev] RE: assert error in print.c

["Joshua Wright" <Joshua.Wright@xxxxxxx>]

Replying to my own post, I know - bad form. ;)

I discovered that the bug comes form the use of the unitialized variable print_args.format in wtap_dispatch_cb_print().  If you want to get a hex dump of the packet without the added information -V information, tethereal used print_args.format instead of the global "static int print_format" variable.

Changing the call to print_hex_data() to use print_format fixed this issue for me.  Patch attached.

Thanks!
