This commit broke the DVD playback for me:

The build host is Linux Mint 18.2 / Core i5-3450 / 8Gb RAM. I build only RPi2 images, so no idea if the issue is present in Generic x86,etc.

If I remove LTO support from kodi/package.mk - DVDs work fine.

Can anyone confirm the issue? The weird thing is that the current Milhouse builds don't have this issue but I can reproduce it 100% when building using normal LE build method or using Milhouse' scripts.

Any ideas? I thought that Linux Mint could be the cause of this weird bug, so I installed Ubuntu Server 16.04 (64-bit). Same issue.

Ubuntu Server for DVD playback? That sounds a bit weird.

Have you tried different DVDs? I get differnt results with different DVDs.

Also my DVD drive seems to be totally allergic to some DVDs (knowing the videos, I don't blame it).

Ubuntu Server as a host OS for LE build system, not for DVD playback.

Maybe I wasn't clear in my original post... The resulting RPi2 images don't play any DVDs (including VIDEO_TS folders and ISOs) unless I disable LTO in Kodi's package.mk. I reported about the issue here a while ago but milhouse have no idea what's causing this.

This issue occur even if I don't make any changes (a clean build from current LE master).
