What's "ldd a.out" telling?
Here is what I get from 'ldd' :
erebus:/home/gpapa05/temp # ldd -r a.out not a dynamic executable
What says "strace ./a.out"?
and for 'strace' :
erebus:/home/gpapa05/temp # strace ./a.out strace: exec: Permission denied execve("./a.out", ["./a.out"], [/* 55 vars */]) = 0
Any idea ??? It seems to me that I have no access to the system library !
Thanks,

No, it could also mean that a.out is on a filesystem that was mounted noexec, i.e. everything on that filesystem can't be executed. That's for instance the default for partitions a user may mount, i.e. partitions having the "user" mount option without an accompanying "exec" in /etc/fstab.

Most likely the partition where a.out is is mounted 'noexec'. If you have 'user' as a mount option you need to have 'exec' after it
