--- Comment #2 from Konstantin Belousov <kib at FreeBSD.org> ---
-o noexec only means that execve(2) with a binary living on that filesystem is
disallowed, -o noexec does not disable mmaping with PROT_EXEC.  So that part of
the bug report is not a bug.

I am interested in the other part, where mprotect(PROT_EXEC) fails to you.  Can
you provide a minimal example which demostrate what you are trying to do and
failed syscall ?  I want a minimal test program in C.
