Ah, I see. I'll look at it in the next days.

I'm not sure if I reported the problem to the list, by the way, so
here it is again:

Build a recent version of my CL-PPCRE stuff
<http://weitz.de/cl-ppcre/> and then compile this function and execute
it:

(defun foo ()
  (let ((regex "abcd*(e|fg)+hij")
        (target "abcddddeefgehij"))
    (loop
      #+:ecl (gc t)
      (let ((start (get-internal-real-time)))
        (cl-ppcre:scan regex target)
        (format t "~,4F~%" (float (/ (- (get-internal-real-time) start) internal-time-units-per-second)))))))

This should result in iterations of the same length (except for GC)
and does so in other CL implementations. However it doesn't in ECL.

The presence or absence of the (GC T) line seems to be irrelevant for
this test. Also, it doesn't really matter which regular expression you
use for REGEX - the more complex it is the faster you see the problem.

Cheers,
Edi.
