How does GLSC release memory?

In other word, how GLSC management memory, while all ability of delete object are removed.
Or GLSC needn’t release memory?
I search this question but it seems to be no relevant exlpanation.
Can someone tell me about this question to find the answer in what section of GLSC_Spec or blog in which url.
Thinks a million.

As far as I know this is not explained explicitly in the spec. However, not releasing memory is kind of a common practice in safety critical systems to avoid memory fragmentation.
