SYMPTOMS
Using FORTRAN PowerStation to compile a program containing records may generate:

fatal error F1002: compiler is out of heap space in pass 2

-or-

fatal error F1001: INTERNAL COMPILER ERROR

(compiler file '@(#)p2symtab.c:1.89', line 1490)

The line number is 1279 when using FORTRAN PowerStation for MS-DOS.



CAUSE
This error occurs only when using the -Zi compiler option, and is related to the number of characters in the names of the structure members and the layout and contents of the structure.



RESOLUTION
There are three different ways to resolve these problems:


 * Reorder the structure. Putting small items first often eliminates both errors. -or-


 * Use one-character-long member names. -or-


 * Recompile without -Zi.



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



MORE INFORMATION
Compiling the sample program with -Zi will generate the "F1002: compiler is out of heap in pass 2" error.

Shortening "xY" to "Y" or increasing 60000 to 70000 causes the F1001 error.

Trimming "x" from "xY" and "xZ" or moving the 60000 element X array to the end of the structure eliminates both problems.

Sample Code
C Compile options needed: -Zi STRUCTURE /CBF/ CHARACTER*1  X (60000) INTEGER*4    xY (4) CHARACTER*1  xZ (1) END STRUCTURE

RECORD /CBF/ CB

END
