The following is ok:
static_castA(*this).fun(); //ok
Because you are creating a rvalue to hold *this which is then bound to a
const lvalue.
The following is an error:
fun(); //err
Because func
The output is different by the optimization.
testcase:
#include stdio.h
struct S
{
unsigned int long long a:33;
};
int main ()
{
struct S x = { -1 };
typeof(+x.a) z = x.a+10;
printf(%llx\n, z);
return 0;
}
result:
$ g++ bug.cpp; ./a

$ g++ -O bug.cpp; ./a

So we do x.a+10 in unsigned long long and then cast it to the bit-field type.
I am thinking we are getting the wrong type for the typeof anyways.

I am running cygwin on Windows XP

The bug also manifests itself on my service provider's CPU.
All values should be 100.0. Minimal program below.

the question is : if a const member function can call a non_const member
function
without const_cast,
if fun() changed the member in A,like this:
//const_test.cpp
struct A
{
A(unsigned int n)
{
aa=n;
}

Thsi is indeed a bug in g++.
the pod() in inherit() is a value-initialization, not a call to
default-constructor.

FWIW my initial attempt here, namely inserting %finput-charset*

to gcc when -combine is not used (my patch handles the -combine
case). This is because

I always thought cross compilers needed GCC to compile anyways so I don't see
why this is a bug?
If you mean while bootstrapping and someone uses --with-tune=native, I still
don't see why this is an issue as that
