@zeroshade I've cracked the mem leaks issue.
The extra code pieces (some are dirty and some asserts are incorrect for maps) I used to find the issues were removed in a single commit (so you can take a look): 0f26525

[candiduslynx]

@zeroshade I guess the value type issue is caused by #35899. Is there some place I can fix the (generated?) code to make it pass?

[zeroshade]

Looks like you've got some tests failing with Too many releases, you can enable that check locally by using the -tags assert flag when you run go test

Yeah, I forgot to remove the extra release for mem buffer (as I moved it to the initialization place): bf0e4a9

[candiduslynx]

@zeroshade I've fixed the extra release in bf0e4a9
I see that one release script test was cancelled (maybe it needs more time?), but the tests are passing

LGTM just one nitpick here

@zeroshade just a mention that everything has passed & it only waits for you to merge
