mimalloc

• Apparently it causes random segfaults when used for everything as LD_PRELOAD in .profile so be careful

• openmandriva is the only distribution that uses mimalloc instead of mallocng: https://github.com/OpenMandrivaAssociation/musl/commit/275cbeb5d0a4874610d36f92bcf66d932a0fa0ff

• jemalloc, mimalloc, and rpmalloc are “modern allocators”

• mimalloc is more than 2.5× faster than tcmalloc and jemalloc

• musl’s new default allocator malloc-ng is based on hardened_malloc:

• No need to have a secure version? Because because all allocators should be secure:

  • https://github.com/struct/isoalloc/blob/master/SECURITY_COMPARISON.MD

• requires cmake to build

TODO

• secure version: https://git.alpinelinux.org/aports/tree/community/mimalloc2/APKBUILD
