MS-DOS
Summary:
SYMPTOMS The Microsoft QuickC compiler versions 2.0, 2.01, 2.5, and 2.51 will hang when a device driver called NAV_.SYS is present in the system. This device driver comes with a package called “The Norton AntiVirus”, version 1.0.0.
The problem occurs when you try to run a program from inside the QuickC integrated environment, either by pressing F5 or by choosing Go from the Run menu. Generally, the following error is generated:
R6000 - stack overflow
QuickC then hangs, leaving the menu bar at the top of the screen.
RESOLUTION The Norton AntiVirus program is loaded from the CONFIG.SYS file with the following statement:
DEVICE = c:\nav\nav_.sys
The only workaround for this problem is to remove the NAV_.SYS driver and reboot before using QuickC.
STATUS Microsoft has confirmed this to be a problem in QuickC versions 2.0, 2.01, 2.5, and 2.51. We are researching this problem and will post new information here as it becomes available.
