SYMPTOMS

Compiling code similar to the code in the sample below may cause the following error to be generated:

fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'E:\utc\src\\P2\main.c', line 379)

RESOLUTION

This internal compiler error can be avoided by using the volatile keyword. In the example below, declaring the local variable, pB, as volatile B* pB instead of B* pb, will work around the problem.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Studio 97 Service Pack 3.
