It's been awhile since I looked into this, but it's not necessarily an easy change. glibc malloc has debugging APIs; a distro can't easily replace it without either emulating the API or patching programs that use it.
- loeg 2y agoNo need to even patch it out. It's relatively easy to change the default, rebuild the world (distros have a flow for this), and restore glibc for the tiny, tiny handful of individual programs that actually rely on glibc debugging APIs. From a end developer perspective: I have no particular familiarity with mimalloc, but I know jemalloc has pretty extensive debugging functionality (not API compatible with glibc malloc of course).
