SuSe Linux 8.1 (with gcc 3.2) or W2k with mingw-gcc 3.2.2
>Description:
Using the attached code gcc returns the following error:
hg@linux:~> gcc -o bf.exe bf.cpp
bf.cpp: In member function `void B::f()':
bf.cpp:11: illegal pointer to bit-field `A::ib'
It should be possible to access a base class member, even if it's a bitfield.
The file bf.cpp contains the following code:
class A
{
public:
unsigned int ib:1;
};
class B : public A
{
public:
unsigned int ib;
void f(){ A::ib=1;}
};
int main()
{
B b;
b.f();
return (0);
}
>How-To-Repeat:
Just copy the code given above to bf.cpp and run
gcc -o bf.exe bf.cpp
