[Bug fortran/15382] New: [gfortran] frontend too lenient when checking variable declarations

[Tobias dot Schlueter at physik dot uni-muenchen dot de]

The following should issue an error in the frontend:
SUBROUTINE BARY()
COMMON /A/ X
EQUIVALENCE (X,Y)
REAL :: Y = 1.
DATA X /1./
PRINT *, X, Y
END
currently it fails with a fatal error in the backend:
[tobi@marktplatz tests]$ gfortran com.f90
com.f90: In function `bary':
com.f90:16: fatal error: gfc_todo: Not Implemented: initial values for COMMON or
EQUIVALENCE
compilation terminated.
