Follow-up Comment #59, bug #55287 (project octave):
@Rik: The strlist is meant for printing tex formated stings, not for caching.
Clearly, I don't understand why strlist.clear(), which is called before each
string rendering, does not free the consumed memory. Also, I don't understand
why this memory increase only happens for the very first axes (clf, will clear
the figure and avoid any further increase of the consumed memory).
I attached a preliminary patch that prevents the strlist from being filled
unless it is actually needed (when text_to_strlist is called). This fixes the
issue for me until I issue a "print" command. At that point I see an increase
of the consumed memory of 20MB, and then the consumed memory becomes more or
less stable whether or not I issue other "print" commands.
(file #46002)
