Whether or not the segfault happens, the code was faulty.  It was trampling a
byte it shouldn't have.  It'd be nice to know why the segfault didn't happen
on FBSD... I suspect it's an uncaught error.

It's very possible that some differences in the memory allocator allowed for
such an access to not cause a segfault (trampling either another malloc()'s
area, or trampling a "canary" or some slop appended to the mallocated memory.

It's most likely not a kernel issue, could be some differences in the libc
and/or the interaction between it and the way perl is built on FBSD.

Keep in mind that FreeBSD is more than just a different kernel... its
userspace libc and the whole kit are built differently.

I'd expect the answer lies in the way userspace memory allocations are done.
