I already indicated that the problem will not appear when the program is compiled with g77. I would be glad to send you the program compiled with the Intel compiler, but a statically linked version of even such a simple program is 245K and only compresses to 115K, so I was not able to send it to this list. Is there another address that will accept this file?
