Series | proposal: disable tcache when using malloc_check | expand |
* DJ Delorie: > This is a fairly trivial change with significant side effects. The > idea is that when one is using malloc_check (via tunables or environ) > correctness and paranoia are favored over performance. Thus, as > tcache bypasses all the malloc_check semantics, it should be disabled > therein so that every malloc/free/etc get the full malloc_check > treatment. > > Does anyone have any opinions for or against this idea? > > * malloc/hooks.c (__malloc_check_init): Disable tcache. I think it's the right thing to do. Thanks, Florian
