Thank you for the nice reproducer. It appears the error occurs related to “import n”. The code compiles when “n” is a dummy argument or when “n” is made accessible in the host scope via USE from a separate module but I do not know if either is a viable work around for you or not. I reported this to Development (internal tracing id below) for further analysis and will update once I learn more.

(Resolution Update on 11/27/2013): This defect is fixed in the Intel Fortran Composer XE 2013 SP1 Initial Release (2013.1.0.080 - Linux)

Pardon the delayed update. I confirmed this internal error was fixed in the Composer XE 2013 SP1 Initial Release (w/ 14.0 compiler) (2013.1.0.080 - Linux) in September.
