SYMPTOMS
Compiling a routine (that uses adjustable sized COMPLEX arrays in an expression with a COMPLEX constant) with the /4Yb (or $debug) option may produce the following error with FORTRAN PowerStation 1.0:
Using FORTRAN PowerStation 1.0a, the following error may be produced:
RESOLUTION
Either use the CMPLX or DCMPLX intrinsic function on the COMPLEX constant, or do not compile with extended error handling.
STATUS
Microsoft has confirmed this to be a problem in FORTRAN PowerStation versions 1.0 and 1.0a for MS-DOS. This problem was corrected in FORTRAN PowerStation 32.
MORE INFORMATION
To demonstrate the problem, compile the sample code below with the Microsoft FORTRAN PowerStation:
Sample Code #1
$debug SUBROUTINE FILTER(FFT1,FFT2,N) complex fft1(n),fft2(n) fft1(n)=(0,1)*fft2(n) return end
The internal compiler error can be alleviated by using the CMPLX intrinsic function as shown in the example below:
Sample Code #2
$debug SUBROUTINE FILTER(FFT1,FFT2,N) complex fft1(n),fft2(n) fft1(n)=CMPLX(0,1)*fft2(n) return end
