What did you try?
I'm putting the following in an emacs -Q *scratch* buffer:
(require 'treesit)
(message "# of buffers before : %d" (length (buffer-list)))
(dotimes-with-progress-reporter (i 10000) "Parsing"
(treesit-parse-string "int c =3D 0;" 'c))
(garbage-collect)
(message "# of buffers after : %d" (length (buffer-list)))
Each time I M-x eval-buffer:
- the list of buffers grows
- the memory usage grows
- loop iterations slow down noticeably
Am I missing something?

No. But note that there are _two_ temporary buffers involved here: one is created in ts-bug.el, and it remains intact and valid; the other is the temporary buffer created by treesit-parse-string. That one is killed by the time treesit-parse-string returns, so treesit-node-start attempts to access positions of a killed buffer! So I think this is a bug in treesit-parse-string: it cannot use with-temp-buffer; instead, it should make the buffer into which it inserts the string part of the parser, so that the buffer is killed and GC'ed only when the parser is no longer referenced. Otherwise the syntax tree returned by treesit-parse-string is unsafe to use.
