SYMPTOMS
Compiling a FORTRAN source file with -Zi that contains a 2 gigabyte (GB) array (or larger) will produce the following error under Windows NT:

fatal error F1001: INTERNAL COMPILER ERROR

(compiler file '@(#)p2symtab.c:1.89', line 1601)

Under MS-DOS, the following error may be generated:

fatal error F1001: INTERNAL COMPILER ERROR

(compiler file '@(#)p2symtab.c:1.89', line 1390)



CAUSE
Although a Windows NT application has a 4 GB address space, 2 of these 4 GB are reserved for system memory. Because a 2 GB array leaves no room for application code, this particular condition was not tested.



RESOLUTION
Reduce the size of the array.

NOTE: Linking a Fortran object module that contains an array 2 gigabytes (or greater) will correctly cause the following warning message under Fortran PowerStation 4.0:


 * warning LNK4084: total image size -2147422208 exceeds max

(268435456); image may not run



STATUS
Microsoft has confirmed this to be a problem in FORTRAN PowerStation 32 for Windows NT version 1.0 and MS-DOS version 1.0 and 1.0a. This problem was corrected in FORTRAN PowerStation 32, version 4.0.



MORE INFORMATION
The following sample illustrates the problem:

Sample Code
c Compile options needed: -Zi c integer*2 n(1073741824) n(1) = 1 end
