The macOS malloc zone advertises version >= 9, for which libmalloc invokes introspect->reinit_lock from the atfork_child handler (_malloc_fork_child) without a NULL check. The introspection struct left reinit_lock unset (NULL), so any fork() in a process that statically links the mimalloc zone made the child jump to address 0 and crash (EXC_BAD_ACCESS at 0x0) on macOS 15. Provide a no-op reinit_lock: mimalloc has no zone-level locks to reinitialize after fork.
fix(osx): implement introspect.reinit_lock to avoid fork() crash
