You forgot to reply to that part ^^^.

Ulrich clearly says:
- mmap PROT_EXEC without PROT_WRITE of anonymous memory
- mmap PROT_EXEC|PROT_WRITE of files

The list will never cover the results of my own calls to make.
Dynamic code generation is not such an unusual capability to add to a
program and it's a very useful tool.  While I can understand
requesting not to do it on the stack, preventing it altogether, and in
particular in areas mmapped explicitely for that purpose, seems rather
excessive.
