Hi,

Since none of us use OpenBSD, it would be super-helpful if you could run the failing binary under valgrind, lldb, or somesuch, and get us an indication of where the use-after-free occurs, and if at all possible where the relevant block of memory was freed (I believe valgrind can do that).

Thanks,

Daniel.
