Is it possible to give it another try with this fix applied and reenable libaacs support?

Great, that's progress, thanks.

However it's crashing for me when playing the 8GB ISO (the crash is immediate, as soon as playback is started).

I'm using the following patch (should be the same as yours, modified to apply on top of libaacs when building OpenELEC):

http://sprunge.us/VWdK

which produces the following crashlog:

Perhaps there are additional places that need fixing now that the loop is exiting early? Although I'm not seeing the "len=0 error detected" debug message, so maybe it's failing before it gets that far? It seems to be crashing in aacs.c: https://gist.github.com/MilhouseVH/bd80fdd1adc505859754

Edit: OK, so libaacs needs a hand before enabling debug logging...
I ran kodi as follows:

Code:

export AACS_DEBUG_MASK=-1
/usr/lib/kodi/kodi.bin  --standalone -fs --lircdev /run/lirc/lircd

and the following is written to stdout/stderr when playing the 8GB ISO:

Without your patch (ie. with unpatched libaacs), the output is:
