Tried a gdb trace, but I'm not that experienced with it. Hope this helps:

George,

Thanks, that's perfect. I think I might have figured out what's going on. I'll get back when I've had a chance to check it through. I might not be able to test as it's not happening on my system and I think it will be specific to certain setups.

What I'll do is generate a fix and post it here for you and the others to try.

Regards
Adam

You're more than welcome Adam. I really like your work on TVH. Thanks a lot for that.

Try this branch on my fork:

https://github.com/adamsutton/tvheadend/tree/issue/redmine-1257

I had failed to clear a couple of ptrs that no longer pointed to valid objects, previously this was fine as they were never used before the relevant ptrs were correctly updated. However to solve a minor issue in new HTSP code for another dev I was not accessing the ptrs and causing it to crash.

Hopefully this will fix the issue.

Adam

It compiles and it doesn't crash on startup but it gives me the same problems as experienced before: https://www.lonelycoder.com/redmine/boards/5/topics/5535

Might be a mistake in my fork, I thought I synced it with master before that commit. I'll check.

Adam

Hi Adam,

I just changed the my master clone from GIT with your changes to src/epg.c I found in your fork and compiled. It works like it should now.

Regards,

George

OK, I'll submit the fix to tvheadend/master.

Adam
