mprotect failed with selinux on fedora 10

[GoogleCodeExporter]

If I run one of the following command from the ypsilon build directory:

  ./ypsilon --sitelib=./test:./sitelib:./stdlib example/gtk-hello.scm

  ./ypsilon --sitelib=./test:./sitelib:./stdlib example/glut-demo.scm

  (strangely the former always fails, while the latter *sometimes* succeeds...)

I don't get any window and instead I get the following output :

src/ffi.cpp:900 mprotect failed 13

and the attached alert from setroubleshooter (alert monitor for selinux).

Looks like selinux thinks ypsilon is doing something dangerous. 

I'm using ypsilon from SVN 20090507 on Fedora 10 i386 (selinux enabled as
default)

Best Regards,
Lorenzo

Thank you for your bug report!
I will install Fedora 10 on my machine and fix the bug. (Ypsilon uses 
'on-the-fly'
code generation for FFI callback, and I think the bug is in there.)
