The latter is the system allocator for a number of BSD distributions; the extension is available under this name for the FreeBSD and NetBSD libcs, and some versions of Bionic (the android libc)." > > note that the part about bionic is incorrect. no version of Android that used jemalloc was built without a linker script explicitly declaring our exports, so even though this was in jemalloc at the time Android used jemalloc, it wasn't exported. My mistake, I'll update in the draft. I also made this mistake with NetBSD, too -- they don't actually export sdallocx as being available to end-users, just declare it in a header.
