Hi,

Did you use Ruby version of StringScanner?  Try

  $ ruby -rstrscan -e 'p StringScanner'

with 0.6.5.  If it prints "StringScanner_R", it is Ruby version.
otherwise ("StringScanner_C") it is C version.

Ruby version and C version is completely *different*,
and C version is bundled with ruby 1.8.

        while ssc.scan_until(SSI_search_re) do

might help.
