When errors happens in DEALLOCATE with STAT the run-time error rises instead setting up STAT variable. For example, following code:
----------------------------- PROGRAM MAIN INTEGER, POINTER :: foo INTEGER IERR DEALLOCATE(foo,STAT=IERR) WRITE (*,*) IERR END PROGRAM ----------------------------- fails with 'Fortran runtime error: Internal: Attempt to DEALLOCATE unallocated memory.' instead of setting IERR.
