Subject: (potential) last_float() / copp-get bug in C ECI

I'm using the C ECI with Ecasound 2.3.0 and I discovered what I thought
was an incorrect behavior with last_float() and copp-get, though I may
well be the incorrect one here. Working around it was really simple and
this probably affects close to null users, but you wanted bug reports...
For the case in question, I was calling a copp-get, then a copp-select,
then a last_float(), which wasn't returning the correct value. The easy
way around that was to call the last_float() in between (ie right after
copp-get, before copp-select), which worked correctly.
The theoretical problem is that since copp-select is supposed to lack a
return value, the last_float() should (in this case) obtain the value
from the last copp-get, even when a copp-select has been called in the
I hope I'm making some sense, depsite my convoluted explanation. I
thought this may extend to other similar command sequences as well.
