struct Store
{
template <typename CheckParentFunc>

It compiles ok if I remove c() call or move update(int) definition body into
class.
g++-4.6.3 works with it.
I changed status to reopened excuse me if I shouldn't do it.

Probably wants a new bugreport, but confirmed:
(gdb) call debug_gimple_stmt (stmt)
__this.0 = __this;
and __this is
<field_decl 0x7ffff5c0c980 __this
type <pointer_type 0x7ffff5c1c888
type <record_type 0x7ffff5c1c2a0 Store type_5 type_6 QI
size <integer_cst 0x7ffff5ae0120 constant 8>
unit size <integer_cst 0x7ffff5ae0140 constant 1>
eh, a bare FIELD_DECL?!
Store::updateChild(const T&) [with T = int]::<lambda()> (const struct __lambda0
* const __closure)
{
struct Store * __this.0;
int & D.2050;
struct Store * const this [value-expr: ((const struct __lambda0 *)
__closure)->__this];
__this.0 = __this;
D.2050 = Store::getStore<int> (__this.0);
possibly confused from this.

Because this bug is so annoying, I thought it may be helpful if I add an
another example:
(clang-3.1 works in all cases)
template <typename value_type>
struct test {
test(std::initializer_list<value_type> l)
{
insert(l.begin(), l.end());
}
template <typename input_iter_t>
void insert(input_iter_t first, input_iter_t last)
{
std::for_each(
first, last, [this](value_type const &v) -> void {
// works on both gcc-4.6.3 and gcc-4.7.2
this->insert(v);
// won't compile on 4.6.3,
// ICE at tree-ssa-operands.c:1035 on 4.7.2
insert(v);
}
);
}
void insert(value_type const &v)
{
std::cout << v << std::endl;
}
};

Frankly, additional examples which are neither self-contained nor minimized
don't help that much. That said, this is a regression and we have already a
minimized snippet, thus we are set. When the bug will be closed, please double
check that the fix works for your code too, thanks!
