FIX: D2030 Internal Compiler Error with /Ox

The information in this article applies to:

• Microsoft FORTRAN PowerStation for MS-DOS, version 1.0

SYMPTOMS

The following error message is generated when the sample code below is compiled for MS-DOS using option /Ox:

   Command line error D2030 : INTERNAL COMPILER ERROR

RESOLUTION

Compile the code from an MS-DOS command prompt under Windows.

STATUS

Microsoft has confirmed this to be a bug in FORTRAN PowerStation for MS-DOS, version 1.0. This problem was corrected in the FORTRAN PowerStation for MS-DOS maintenance release, version 1.0a.

MORE INFORMATION

FORTRAN PowerStation, version 1.0, can be differentiated from the maintenance release, version 1.0a, by invoking the linker. Typing "link32 | more" from the \F32\BIN directory will show version 2.8 for FORTRAN PowerStation, version 1.0, and will show version 1.0f for the maintenance release, version 1.0a.

The following sample code illustrates this problem:

Sample Code

C compile options required: /Ox

      COMMON/FLOWED/QCURVE(1,3,26),NATUR
      DIMENSION DUMMYS(3,26)
 1800 IF(QCURVE(NATUR,2,I).GE.AA) THEN
        DUMMYS(3,K) = QCURVE(NATUR,3,I-1)
        IF(K.EQ.26) GO TO 1810
      ELSE
        I  = I + 1
      ENDIF
      GO TO 1800
 1810 DO 1850 I = 2,25
 1850   QCURVE(NATUR,3,I) = DUMMYS(3,I)
      END
