[Bug fortran/30411] gfortran MODULE bug for non trivial data types

[kargl at gcc dot gnu dot org]

------- Comment #1 from kargl at gcc dot gnu dot org  2007-01-09 01:26 -------
If you move the module unit above the main program, so that the 
module has been compiled by the time the main USEs it, then with
gfortran 4.3.0 I get

laptop:kargl[211] gfc4x -c n.f
n.f: In function 'distance':
n.f:5: warning: Function return value not set
n.f:26.22:

           L=Distance(Point1,Point2)                                    
                     1
Error: Type/rank mismatch in argument 'point1' at (1)

which is correct.   Furthermore, if I move the define of
the derived above the CONTAINS and remove the private 
version in the function and subroutine, I get

laptop:kargl[217] gfc4x -c n.f
n.f: In function 'distance':
n.f:10: warning: Function return value not set

which is the expected output.  

In short, grab a newer version of gfortran from the gfortran
wiki or build gfortran for the 4.2 or 4.3 branch.  Additionally,
your code needs some improvements.
