How does FreeBSD compare vs OpenBSD on that aspect?

Probably the same (or worse) as Linux. IIRC FreeBSD still had executable stacks by default until at least 2016?

Edit: I give FreeBSD too much credit.

The kern.elf64.nxstack / kern.elf32.nxstack sysctls were introduced in FreeBSD 9.0, which is 0 by default. 1 enables PT_GNU_STACK behaviour. Apparently not implemented for all platforms. So you get to choose from executable stacks by default and the same nasty behaviour Linux has.
