Yes

Yes, there must be a bug on bugzilla ATM I've no trace of.  A colleague
of mine did some investigation in the past and discovered IIRC that the
GCC driver was the main source of the leakage. I'm Ccing him now
hopefully he recalls/knows more than me.

Also I think there was some fixing in this area but even in case is
fixed completly now we'll have to cope with older version for a while.
