Ah, I see, thanks! Please try to build with:

  CFLAGS="-fpie -pie" ./configure …

Cf. <https://www.openbsd.org/papers/asiabsdcon2015-pie-slides.pdf>.

php doesnt compile for me at all, I use the package.

I get wx violation just trying to compile it, and that netbsd patch use some paxctl which openbsd
doesnt have.

No. Actually it appears to be the very same issue:

 * this ticket: mmap W^X violation
 * the other ticket: it does not allow mapping pages both writable and
   executable

Martin, could you please check whether the patch attached to the other
ticket would solve the issue for you?

ehm, I don't know sorry. Thought https://bugs.php.net/bug.php?id=72281 was a
compilation error?
