--- Comment #5 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
Same ICE, different pattern on X86_64:
trippels@gcc67 ~ % cat PPCAsmParser.ii
struct A {
int operator[](int) const {}
};
struct B {
void m_fn1();
};
struct C {
virtual bool m_fn2(int, unsigned &, A &, int &, unsigned long &, bool);
};
template <class MCAsmParserImpl> struct D {
D(int) { MCAsmParserImpl(0, 0, 0, 0); }
};
int a;
namespace {
struct F : C {
bool m_fn2(int, unsigned &, A &, int &, unsigned long &, bool);
unsigned m_fn3(const A &, B &);
F(int, int, int, int) {}
};
}
bool F::m_fn2(int, unsigned &, A &p3, int &, unsigned long &, bool) {
B b;
m_fn3(p3, b);
}
void fn1() { D<F>(0); }
unsigned F::m_fn3(const A &p1, B &p2) {
for (int *p;; p++)
switch (*p) {
case 0:
p1[a];
case 1:
p2.m_fn1();
}
}
