The following program does not compile with PGI version 14.9 with optimizing flags (-fast). Without optimizing flags it does compile, and it compiles with both gfortran and intel fortran.
I get the following error from PGI:
Lowering Error: unexpected data type at load [ast=62,asttype=38,datatype=0]
Lowering Error: unexpected data type at assignment [ast=169,asttype=17,datatype=0]
