Subject:Store leaks (drip drip...) 
From:Robin Popplestone 
Volume-ID:931126.01 

Gordon Dakin is suffering a store leak on a POP program for vision
that we have been writing. It gets a run-out-of-memory message after about
half an hour of taking pictures, analysing them and reacting to them. It takes
several big pictures per minute.

(i) The program, I seem to recall, turns over a lot of widgets (several a
minute). Could that be a problem?

(ii) Are there any tools available to help localise the problem. E.g. one
might do a kind of garbage collect analogue to discover how much store
was hung on a particular variable.

Robin.
