Wireshark · Wireshark-dev: Re: [Wireshark-dev] mergecap seg-faulting in master

[Michal Labedzki <michal.labedzki@xxxxxxxxx>]

Ok, I know this one.

mergecap.c has merge_open_in_files()
merge_open_in_files() use wtap_open_offline()
wtap_open_offline() need init_open_routines(); // before use

So add init_open_routines(); before merge_open_in_files() solve issue.
But... it seems that before use libwiretap we should do
init_open_routines()... file.c use merge_open_in_files() and may be
affected too. To be continue... ("don't have time to look at it at the
moment" - me too)
