Why?  That's IMHO the expected result.
If you modify your testcase, so that it does only:
  p = "^(.?)(.?)(.?)(.?)(.?).?"
    "\\5\\4\\3\\2\\1$";
(so that it finishes in reasonable time)
and run it against vanilla CVS, you get:
m[0] = "civic"
m[1] = "c"
m[2] = "i"
m[3] = ""
m[4] = ""
m[5] = ""
m[6] unused
m[7] unused
m[8] unused
m[9] unused
