C7 Module, Overlay, and Run-time Module Makes Computer Hang

• Microsoft Visual Basic Standard and Professional Editions for MS-DOS, version 1.0

SYMPTOMS

Programs hang when they use all of the following: overlays, a Microsoft C/C++ version 7.0 module, and a run-time module.

WORKAROUND

To work around this problem, use one of these options:

• Compile for stand-alone (BC option /O).



• Do not use overlays.



• Do not use C modules.

STATUS

MORE INFORMATION

Steps to Reproduce Problem

1. Type the following code into a source module called MOD1.BAS:

   
         'MOD1.BAS
    
         Declare Sub csub cdecl()
         Call csub 




2. Compile the Basic module by entering the following command from an MS-DOS prompt:

   
         BC MOD1.BAS; 




3. Using the following code, create a C program with Microsoft C/C++ Version 7.0, and name it MOD2.C:

   
         /* MOD2.C */ 
         #include <stdio.h>
         void csub()
         {
            Printf("In the C Subroutine\n");
         } 




4. Compile the C module from the MS-DOS prompt by using this command:

   
         CL /c /AL MOD2.C 




5. Link the program in the following way:

   
         LINK MOD1.OBJ (MOD2.OBJ); 




6. Run the MOD1.EXE program from the MS-DOS prompt.
