--- Comment #13 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note the pool was made dynamic (and effectively larger) exactly for a QOI
issue...
[the dynamic nature is to make its size controllable by the environment, sth
that didn't materialize yet]

The difficulty with freeing is that it is necessary until the dynamic loader
can get rid of the C++ runtime.  There isn't a way to enforce releasing at that
point
(apart from making it static storage).
