[Linux-ia64] mprotect??

[D'laila Pereira]

Hi
I am running a program on Linux (tried on both TurboLinux, and Redhat
linux) ,itanium machine , that needs to "mprotect" (PROT_READ or
PROT_RD/WR, depending on the certain parameters) a sequence of pages. What
i noticed is that "mprotect" works at times, but does not take affect at
other times. What is the cause of such random behaviur of mprotect.?
Does mprotect work for Linux Itanium, or there is some problem with it ?

thanks
d'laila

D'Laila-

We need a lot more detail than this.  In general, yes, mprotect works.
This system call is used extensively by the shared library loader.

Are you running an IA32 or IA64 program?  The output of an `strace'
from one of your failing runs would be helpful.
