I don't see it with i386 FC5 with ghc-6.4.2, but I received a report 
on it for x86_64 FC5 when selinux is enforcing.

Today I tried ghc-6.4.2.20060619-x86_64-unknown-linux on x86_64 
FC6test1 with enforcing selinux however and still get:

ghc: internal error: getMBlock: mmap: Permission denied

from the rts.  ("setsebool allow_execmem 1" works around it.)
