We've started rolling out the new CDM, so this makes sense (that bug may stay open while we work on some more incremental changes).

I'm not able to reproduce this on my Mac, but I'm on 10.13, rather than 10.11. Looks like it's crashing inside the Widevine CDM lib. Given the crash reason (EXC_BAD_INSTRUCTION / EXC_I386_INVOP), I wonder if the machine is in some state that's unexpected by Widevine. However, since the CDM is a black box, it's hard to be sure.

I'll reach out to Widevine.

Widevine have confirmed this is a known issue with the CDM and older Mac hardware. They're working on providing an updated CDM with a fix. This means we're going to need to do a minor bump of the CDM once the update is available to us.

I tested this issue on iMac 10.11 with FF Nightly 64.0a1(2018-10-09) and I can't reproduce the crash, please let me know if there are some specific steps or sites where this crash occurs. Also the WidevineCdm Version: 4.10.1146.0.

Bug 1499880 covers the changes for updating to the new CDM to fix this issue. We first landed the new CDM in 65, and have now updated Balrog rules and uplifted changes to fix 64.
