Article: Q149512
Product(s): Microsoft Fortran Compiler
Version(s): 4.0
Operating System(s): 
Keyword(s): kbCompiler kbFL32 kbFortranPSkbbuglist
Last Modified: 03-NOV-1999

-------------------------------------------------------------------------------
The information in this article applies to:

- 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
  ! comment the following line for work-around
        f = 'hello'  ! This line causes the assertion failure
  ! uncomment the following line for work-around
  !      f%s = 'hello' ! Ok, assignment to character variable member
        print *, f
        end
