Actually, I'll include the other slightly different testcase here, since it'll
probably be the same problem. If you prefer me reporting it as a separate bug,
I will do so.
$ cat bug.ii
template <class T>
static inline bool Dispatch (T* obj, void (T::*func) ())
{
(obj->*func) ();
}
class C
{
bool f (int);
void g ();
};
bool C::f (int n)
{
bool b;
switch (n)
{
case 0:
b = Dispatch (this, &C::g);
case 1:
b = Dispatch (this, &C::g);
}
}
void C::g ()
{
for (;;) { }
}
$ gcc -c -O bug.ii # works
$ gcc -c -O bug.ii -g
bug.ii: In member function ‘bool C::f(int)’:
bug.ii:11:6: error: control flow in the middle of basic block 4
bug.ii:11:6: internal compiler error: verify_flow_info failed
