There's a patch in comment #3 of that > PR that addresses a similar issue. Hi Steve, Yes, that's one and the same issue. One neat feature that will emerge from adding an 'assigned_at' field to gfc_symbol is that the fortran front end can issue a "used uninitialized" warning if -Wuninitialized is not set. For example: integer :: i, j i = 1 i = j print *, i end nagfor issues by default: Warning: test.f90, line 5: Symbol J referenced but never set Cheers Paul
