Something went wrong with the attachement, so I'll repeat it here:
I was compiling the following .cpp file with -fPIC -mregparm=3
on gcc 3.1 and gcc 3.2:
class A {
virtual void f1();
};
class B {
virtual void f2();
};
class C : public A, public B
{
virtual void f1();
virtual void f2();
};
void C::f2() {}

>Description:
Compiler generates internal error when compiling the attached .cpp file with flags -c -fPIC -mregparm=3
For gcc 3.2, the generated error is slightly different:
Internal compiler error in x86_output_mi_thunk, at
config/i386/i386.c:12615
>How-To-Repeat:
Compile the attached .cpp file using gcc 3.1 or 3.2 and flags
-c -fPIC -mregparm=3
>Fix:
Check sourcecode in cp/method.c:412 where thunk is generated
( config/i386/i386.c:12615 for gcc 3.2)
When compiling with -mregparm=2 everything goes ok
