[mythtv-users] mythfrontend on mac segfault

[brad dreisbach]

I am a bit behind reading mythtv-dev, are there any known issues related to running a master fronted on mac(wasn't
able to turn up anything searching trac)?

I seems to dump a core when started up with upnp enabled on the frontend.  when i start it using --noupnp
it will "work" to a certain extent, but segfaults exiting watching a recording.  i am compiling using osx-packager-qtsdk.pl.

figured id ask if this is a known issue before digging deeper…

cheers,
