You're working on a implementation of allocatable dummy arguments in 
gfortran?

Different constraints apply to the use and the compiler. The compiler 
must check that this condition is satisfied, and issue an error 
otherwise. The user has to write code that satisfies this constrain, 
otherwise his code will be rejected by any decent compiler.
