As our moderator pointed out, sounds like NX. Use mmap() with PROT_READ|PROT_WRITE|PROT_EXEC or just PROT_WRITE and then mprotect() your region to PROT_READ|PROT_EXEC. If you're on an i386, then it's probably some kernel hardening patch that makes the heap non executable. ./ck -- Chariton Karamitas Electrical and Computer Engineering Department Fuculty of Engineering Aristotle University of Thessaloniki, Greece
