Error using tapset functions, i.e. euid()

[Serge Hallyn]

When I try to use this script:

probe kernel.function("sys_open").return
{
# -EPERM or -EACCES
        if ($return == -1 || $return == -13) {
                printf ("%s(%d) %s (%d) %s\n",
                                execname(), pid(), probefunc(), $return, kernel_string($filename))
                printf("euid %d\n", euid())
        }
}

I get a long list of errors beginning with:

This bug was fixed in the package systemtap - 2.1-1~experimental1

---------------
systemtap (2.1-1~experimental1) experimental; urgency=low

  * New upstream release (Closes: #690404, #701365, #701365)
    (LP: #803549, #1130626, #1075772).
  * Drop patches that are part of the new upstream release:
    - manpage-syntax1.diff
    - spelling-fixes1.diff
    - spelling-fixes2.diff
    - manpage-paths1.diff
    - fix.CVE-2012-0875.diff
  * Add patches that fix various lintian warnings. These have all
    been accepted upstream so we can get rid of them in the next
    release (thanks Frank Ch. Eigler!):
    - 0001-man-stap.1-escape-minus-sign-properly.patch
    - 0002-man-stap.1-fix-typo.patch
    - 0003-man-stapprobes.3stap-escape-minus-sign-properly.patch
    - 0005-Add-missing-usr-bin-env-stap-to-some-examples.patch
    - 0006-man-stappaths.7-properly-escape-dot-in-the-beginning.patch
    - 0008-man-escape-quote-properly-in-header.patch
    - 0001-configure.ac-remove-temporary-file-after-test.patch
    - 0002-Makefile.am-remove-temporary-symlinks-in-distclean.patch

  * Add patch to partially fix #604453:
    - 0001-blacklist-more-unsafe-functions.patch
  * Backport patch to support unreadable System.map on Ubuntu:
    - 0001-translator-tolerate-unavailable-System.map.patch
  * Add patch to suggest reading README.Debian if anything
    fails. Usability testing shows that surprisingly few users
    will find it otherwise :-) This patch can not be forwarded
    upstream but it is very simple.
    - suggest-readme.debian.diff
  * Upload to experimental since wheezy is frozen.
  * Drop systemtap-grapher binary package as it has been
    removed by upstream. Remove its build-dependencies
    libgtkmm-2.4-dev, libboost-dev and libglademm-2.4-dev as well.
  * Add powerpcspe to the architecture list (Closes: #700161).
  * Ship stap-prep to help users figure out what
    debug symbol and header packages they need to install and mention
    this in README.Debian.
  * Add patches to make stap-prep work on Debian:
    - 0001-Prepare-stap-prep-for-support-for-non-rpm-systems.patch
    - 0002-stap-prep-add-support-for-deb-based-systems.patch
    - 0003-man-add-man-page-for-stap-prep-1.patch

  * Enable emacs addon that makes editing .stp files easier.
  * Ensure that build log shows full build commands.
  * Bump Standards-Version to 3.9.4, no changes were needed.
