Is this using mimalloc redirection?

I think I know what is the cause; thanks for reporting! The workaround would be to disable verbose, or comment out just the 2 verbose calls in `mi_reserve_os_memory_ex` (in `arena.c`)....

I tried to repro this with both the latest `dev` and `dev-slice` branch, both with dynamic overriding and static overriding and I could not reproduce it. Maybe it has been...
