I'd been hoping this was specific to 18.x, but no such luck.  We'd just 
settled on 17.4 in large part due to the number of times we've heard that 
it's received "extra QA", although issues like this make me wonder.

PIC isn't critical -- wasn't available on the platforms we're replacing -- 
but I'd be more forgiving if it was a new feature in this code, rather 
than a regression.

Agreed.  Worse still is the near impossibility of getting regressions 
fixed in a timely fashion, especially without starting over with a new 
case for each affected platform / device.  I've all but given up trying.
