The following program has a problem as the passed array is shorter than the array expected by the subroutine. Currently, gfortran does not detect this problem.

(NAG uses not -C=array but -C=call for this.) The reason is that some programs (e.g. Exciting.sf.net) passes an array(n-1) to a subroutine foo(n,b) with "real :: b(n)" but only accesses the first n-1 elements. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27989 ^ permalink raw reply [flat|nested] 5+ messages in thread
