Code generation bug in -parallel

The attached program (which is actually C) produces incorrect output if and only if -parallel is specified, irrespective of the number of threads and what seems to be consistently.  However, there is a difference between 13.1.2.183 and the beta, though both are incorrect.  It works in its Fortran version (not included) and under gcc.  To test it, run the command 'show N', where N is the number of iterations (I recommend 1).  That shows that it is corrupting the data indexed by the lower bound(s).

File renamed as Bug_1.tgz for the poor little Web script.

>>...File renamed as Bug_1.tgz for the poor little Web script. That's OK and IDZ uploading subsystem verifies for some extensions and renames some of them ( the list of supported extensions provided below the editor's box ). Thanks for the report and test case.
