error message relating to assumed size dummy argument could be improved

[Jean_U]

The following is just a suggestion to improve error diagnostics.

The compiler correctly fails with an error on the attached code but the error message is less helpfull than it could be:

t1.f90(9): error #5536: Array bounds information needed, but not available for assumed-size array
subroutine foo(x,y)
-----------^
compilation aborted for t1.f90 (code 1)

The actual issue is that the type definition for the dummy argument y has a default initializer which
conflicts with the fact that y is both intent(out) and assumed size.

An error message stating at least which argument has the problem would have helped with the original scenario in which I had multiple assumed size arguments. I hadn't run across this problem before and assume
it is infrequent. Without a nicer error message it took me quite some time to diagnose the actual
problem.

I submitted a feature request (internal tracking id noted below)to consider adding thearray name to the error diagnostic. I will update the thread as I learn more.

Your request to indicate which argument the error applies to is fulfilled in the Intel Fortran Composer XE 2011 Update 7 (2011.1.1.256 - Linux).

Your example now generates the following error:
