SYMPTOMS
Using Microsoft FORTRAN version 5.0 or 5.1 to compile a program with the /Gt compiler option can result in the following error:

fatal error F1001: Internal Compiler Error

(compiler file '@(#)omf.c:1.60', line 185)

This specific problem involving the /Gt compiler option has been encountered only in code that contains FORMAT statements and array declarations. Using a smaller or larger data threshold value, slightly modifying a format statement, or changing an array bound will suppress the error.

NOTE: The /Gt option is not supported in FORTRAN PowerStation, so this is not a problem in FORTRAN PowerStation.



STATUS
Microsoft has confirmed this to be a problem in FORTRAN versions 5.0 and 5.1.



MORE INFORMATION
The following sample program illustrates the problem: integer ii(380), jj(381,42) read(*,'(1x,1i1)') ii(1) end Compiling this program with /Gt1520 will generate the error. However, compiling with a data threshold value less than 3 (for example, /Gt2) or greater than 1520 (for example, /Gt1521) suppresses the error.

Changing the bound of array ii or modifying the format of the read statement also suppresses error, as illustrated below: integer ii(381), jj(381,42)  ! Change bound of array ii. read(*,'(1x,i1)') ii(1)      ! Modify inline FORMAT statement. end This is one of the simpler code samples that exhibits this error. The particular /Gt value that causes the problem is different for other programs that result in this error.
