BUG: ASSERT Failure with String Assigned to User-Defined Type

• Microsoft Fortran PowerStation for Windows 95 and Windows NT, version 4.0

SYMPTOMS

The compiler generates the following assertion failure message when you make a direct assignment of a character string to a user-defined data type structure variable:

   Assertion failed:
   (NTYPE(symbolptr->_var.initial.whole_value)==N_STRUCTURE_CONS) ||
   (((NTYPE(symbolptr->_var.initial.whole_value) == N_ARRAY_CONS) ||
   (NTYPE(symbolptr->_var.initial.whole_value)==N_ARRAY_SECTION)) &&
   (symbolptr->_name.xdim != NULL)), file err_geninit.c, line 648

   abnormal program termination

RESOLUTION

Assign the character string to a corresponding user-defined data type structure character variable member.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Sample Code to Illustrate Problem

! Compile options needed: none

      type A
          character*8 s
      end type
      type (A) f

      f = 'hello'  ! This line causes the assertion failure

      print *, f
      end
