636	irregex behaves differently with overlapping character sets on some machines	sjamaan	felix winkelmann	"We haven't figured out the cause or anything else yet, but on my NetBSD box, I get the following (expected and correct output):

{{{
#;1> (use irregex)
; loading library irregex ...
#;2> (irregex-match 
        '(seq (* white) (submatch (+ print)) 
              (* white) "":"" (+ white)
              (submatch (+ print)) (* white))
     ""io:event-dispatch"")
#f
}}}

On call-cc.org (and on another of Mario's machines which is x86-64 Linux) we get this:

{{{
#;1> (use irregex)
; loading library irregex ...
#;2> #;2> (irregex-match 
        '(seq (* white) (submatch (+ print)) 
              (* white) "":"" (+ white)
              (submatch (+ print)) (* white))
     ""io:event-dispatch"")
#<regexp-match (2 submatches)>
#;3> (irregex-match-substring #2 1)
""i""
#;4> (irregex-match-substring #2 2)
#f
