[Bug fortran/42999] New: [4.5 Regression] bogus error: Parameter 'i' at (1) has not been declared or is a variable, which does not reduce to a constant expression

[jv244 at cam dot ac dot uk]

This could should compile, I believe

 TYPE DD
  INTEGER :: I
 END TYPE DD
 TYPE(DD) :: X(2)=(/(DD(I),I=1,2)/)
 END

but does not with current 4.5 trunk, fails with:

Error: Parameter 'i' at (1) has not been declared or is a variable, which does

I think it regressed between 2010-01-07-r155688 and 2010-01-10-r155780

Jerry, I think that is due to your initializer patch:

------- Comment #3 from jvdelisle at gcc dot gnu dot org  2010-02-09 03:41 -------
I was being a bit too aggressive. The following patch fixes it.  The problem
does not exist on fortran-exp. I removed my original patch from the branch
since handling of constructors is being revamped completely. The fortran-dev
branch will pick this up on the next merge from trunk.

Regression tested fine and I will commit tomorrow evening (PST)
