No it has not gone.

It is only hidden. That means you lowered the likelihood of it happening.

The code still accesses an object that does not exist. That means random 
memory.
Without heaptrc, you simple got better likelihood, that this random 
memory contains data, that does not cause a crash.
But the bug is still there. It may still crash...

Since it happens at form close, maybe you freed some component in your code?
Changed owner of a component (moving to other form)?
