[Bug fortran/31011] Incorrect error: parameter array sections

[pault at gcc dot gnu dot org]

------- Comment #1 from pault at gcc dot gnu dot org  2007-03-07 09:41 -------
confirmed - this is an arithmetic error in expr.c(find_array_section).

The following fixes the problem, although it has not yet been regtested.
