[Bug fortran/20902] New: error needed

[jv244 at cam dot ac dot uk]

The following is non-standard and the compiler should probably generate a
warning/error with '-pedantic -std=f95'

TYPE T1
 sequence
 integer :: i=1
END TYPE T1
TYPE T2
 sequence
 integer :: i=2
END TYPE T2
TYPE(T1) :: a1
TYPE(T2) :: a2
EQUIVALENCE(a1,a2)
write(6,*) a1,a2
END
