SYMPTOMS
Compiling the sample code below with Visual C++ 32-bit Edition causes
the compiler to generate the following error message:
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 602)
The compiler should instead generate the following error:
error C2064: term does not evaluate to a function
Compiling the sample code with Visual C++, version 1.5, under Windows
NT gives the following error message:
fatal error C1001: internal compiler error
(compiler file 'msc1.cpp', line 585)
Again, "error C2064: term does not evaluate to a function" should display.
When the code below is compiled with Visual C++, versions 1.0 and 1.5
under Windows 3.1, no errors are generated. The compiler effectively
ignores the erroneous line. If we compile at warning level 4 (CL /W4),
the following warning is generated:
warning C4100: 'push_this' : unreferenced formal parameter
This warning shows that the erroneous line was ignored.
STATUS
Microsoft has confirmed this to be a bug in the products listed at the
beginning of this article. This bug was corrected in C/C++ compiler version
9.0, included in Visual C++ 32-bit Edition, version 2.0.
Sample Code
// Compile options needed: none
#include <iostream.h>
class stack_class {
int stack_data[10];
int stack_ptr;
public:
void init(void);
int push(int push_this);
};
void stack_class::init(void) {stack_ptr = -1;};
int stack_class::push(int push_this)
{
if (stack_ptr >= 99)
return(0);
//ERROR: (++stack_ptr) - Change to [++stack_ptr]
stack_data(++stack_ptr) = push_this;
return(1);
};
void main()
{
stack_class stack;
stack.push(100);
}
