I'm still on the Feb 3 nightly, but I just started having stock alarm clock problems too. Specifically, when the alarm goes off, the screen turns on but there is no sound or vibration. I turned all my volume levels up and tested it again, but it didn't help (and the lack of vibration seems to be an indication of a deeper problem anyways).
After some googling, I decided to force stop + clear data on the Clock app. I then added a new test alarm, and it worked!
The problem is that I'm sure it will get into that state again. Maybe I will upgrade to the latest nightly and hope for the best, but it sucks being 15 minutes late to work
If it happens again, I'll probably try a third-party alarm clock app, as I'd rather not have to clear data on the clock app every night just to be safe
