[Bug uprobes/10595] uprobe probes causes selinux failures

["fche at redhat dot com" <sourceware-bugzilla@sourceware.org>]

------- Additional Comments From fche at redhat dot com  2009-09-10 15:49 -------
I can't seem to reproduce this exactly on a pretty plain rawhide x86-64 box:

sudo ./stap -e 'probe process("./stap").function("*").return {}' -t -c './stap -V'
WARNING: u*probe failed stap[1567]
'process("/notnfs/BUILDg3/stap").function("~basic_stringbuf@/usr/lib/gcc/x86_64-redhat-linux/4.4.1/../../../../include/c++/4.4.1/iosfwd:63").return'
addr (null) rc -22

But here comes dmesg:
