SYMPTOMS
========
Compiling a C++ file that contains an explicit call to a base class conversion
operator, with the /FR compiler option (create Browser information) may result
in the following fatal compiler error:
C:\Test\Test.Cpp(22) : fatal error C1001: INTERNAL COMPILER ERROR (compiler
file 'msc1.cpp', line 899)
RESOLUTION
==========
There are two possible workarounds:
- Turn off "Generate browse info" or remove /FR compiler option.
-or-
- Provide an implicit call to the base class conversion operator as
demonstrated by the following sample code.
Sample Code
-----------
/* Compile options needed: /FR
*/
class Base
{
public:
operator int()
{
return 0;
}
};
class Derived : public Base
{
int fun()
{
return Base::operator int();
// The following line is a workaround for the
// previous line that fails.
// return int(*((Base*)this));
}
};
