The information in this article applies to:
- The C/C++ Compiler (CL.EXE), included with:
- Microsoft Visual C++, 32-bit Editions, version 4.04.1
- Microsoft Visual C++, 32-bit Enterprise Edition, version 4.2
- Microsoft Visual C++, 32-bit Professional Edition, version 4.2
-------------------------------------------------------------------------------
SYMPTOMS
========
When using extern in a function call, the compiler generates an Internal
Compiler Error (ICE). A syntax error should be generated instead.
When specifying an illegal type in a function prototype within a function, the
compiler generates an ICE. A syntax error should be generated instead.
Both of the above situations result in the following error message when using
Visual C++ 4.0:
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 899)
When using Visual C++ 4.1, the error message in both situations is the
following:
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 1090)
When using Visual C++ 4.2, the error message in both situations is the
following:
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 1089)
RESOLUTION
==========
Do not use extern in a function call.
Specify a legal type in the argument list of the function prototype.
STATUS
======

//Code sample 1
int func(int);
void main () {
extern func(1); //C1001 (ICE) on this line; "extern" is illegal
}
//Code sample 2
int func(int);
void main () {
extern int func(1); //C1001 (ICE); "1" is an illegal type
}
