Comment 20 for bug 2024003

arm64 (and some x86_64 if I remember well) has execute-only enforced in hardware. It means that the memory where the executable code is, isn't readable.

it was enforced in 7.3.

Regarding sbcl, a thread on ports@ mailing-list mentioned it: https://marc.info/?l=openbsd-ports&m=167483553608781&w=2.

Passing --no-execute-only to the linked is the simpler fix. The (better) other way would be to make sbcl to not required to read the code segment.
