Hi Andrew,

When changing this, to be more in line with the "HV" code...

diff --git a/cinelerra-5.1/cinelerra/playbackengine.C

...will result in a fix for the memory leak, but does cause a warning 

Garbage::~Garbage: title=CICache users=1 was not deleted by 

This was changed with f5725c7e (7/4/20). But also shows that many unrelated 
changes cause real issues to hide. I found this by hand, not even using git 
bisect. I understand the urge for the garbage collector, but for some 
reason not behaving. What I notice is that the 'last' object is empty when 
it is actually destroyed by the garbage collector (~CICache). What is the 
best way going forward?
