Summary: Add runtime diagnostics for SIZE intrinsic function Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: libfortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: thenl...@users.sourceforge.net As has been brought up before (Bug 20406), the SIZE intrinsic returns an unpredictable result if the argument is an unallocated allocatable or a pointer that is not associated. While this is perfectly standard-conforming behaviour, it would be helpful in program development to have SIZE throw a runtime error if this condition occurs. I.e. SIZE should first check if an array is ALLOCATED or a pointer is ASSOCIATED and abort with a runtime error if that is not the case. Fortran 2008: 13.7.156 SIZE (ARRAY [, DIM, KIND]) 3 Arguments. ARRAY shall be an array of any type. It shall not be an unallocated allocatable variable or a pointer that is not associated. If ARRAY is an assumed-size array, DIM shall be present with a value less than the rank of ARRAY.
