possible bug with !DIR$ directive and option /stand:f08

Take the following code:

subroutine test
	!DIR$ ATTRIBUTES DLLEXPORT :: test

    print *,"if this line exceeds 132 characters, the directive makes the compilation fail if using /stand:f08                                 1"
end subroutine

if I compile it with

ifort sub.f90 /c

I get no warnings or errors.

If however I compile it with 

ifort sub.f90 /c /stand:f08

I get:

C:\TEMP\x>ifort sub.f90 /c /stand:f08

If I remove the !DIR$ directive I get a warning about the line length, but no error
