--- Comment #1 from Jonathan Lebon <jlebon at redhat dot com> ---
Fixed in this commit:
http://sourceware.org/git/gitweb.cgi?p=systemtap.git;a=commitdiff;h=d03bc68e1f7050ba5dfeabbe3e40c43b24f1f283

The 'len' parameter passed to _stp_text_str() was incorrectly set to 1 higher
than need be. The function _stp_text_str() does not count the trailing NULL. In
contrast, the function _stp_strncpy_from_user() does, which is also used in
this tapset, in which case 'len' should indeed be incremented (see e.g.
user_string_n()). This may have been the source of the confusion.
