Segmentation Fault on LIRC change in 17972

After building CVS version 19792, I get the following error upon startup of mythfrontend

Sorry, forgot to enter email address

[danielk]

Did you try doing a "make distclean" ?

Also what version of lirc is this with?

[eric.bosch@…]

Yes, this was after distclean, on two different machines, one Gentoo, one Ubuntu. Lirc is version app-misc/lirc-0.8.3-r2 on Gentoo, and version 0.8.3-pre1 on Ubuntu.

[eric.bosch@…]

It appears to work again after 17978.

[danielk]

Eric, can you try the patch on #5583.

Replying to danielk:

Eric, can you try the patch on #5583.

Yes, here you go. If there is any other debug info I can provide, let me know

With mythfrontend -all, here's the info... I pulled up the record in mysqlnavigator, and it does exist, but 'LircKeyPressedApp?' is empty.

Is this still a problem? It seems to work fine for me.

[eric.bosch@…]

I don't believe it is a problem any more. You can close the ticket. I'm running 19037 now problem free. I believe I had a library issue at that point.
