Follow-up Comment #49, bug #55287 (project octave):
@Rik: I have spent a bit of time trying to track this issue but I'm afraid I
didn't go far, especially since the actual bug is not well defined.
Let me explain: My main test is the one I posted in comment #41. This test
gives me numbers that are quite reproducible on my dev machine, with ASAN
enabled (See the figure attached to comment #41). The results I get on another
machine, with the same script but without ASAN, are very different (See
attached figure):
* The test runs much more rapidly without ASAN, no surprise here,
* The used memory is 7-8 times smaller without ASAN: this tends to show that
the ASAN itself consumes memory that would otherwise not be an issue,
* Without ASAN, if I use "plot" instead of "set" the timings are very
different but the Used memory stops growing indefinitely after the first
"clf", which tends to confirm the statement in comment #37.
Can we agree on a reproducible test, using the very handy "memory" function
attached to this report? Can we agree on the fact the ASAN is of no use here
since there is no unfreed memory to track? Then only
