The following invalid code snippets are accepted on mainline:
========================
struct A
{
A(...) = default;
};
========================
========================
struct A
{
A(const A&, ...) = default;
};
========================
Apparently defaultable_fn_p in cp/class.c doesn't handle the ellipsis
correctly. This makes me wonder whether type_has_user_nondefault_constructor
which contains similar code has the same problem.
This bug can be exploited to trigger an ICE:
========================
struct A
{
A(...) = default;
A(const A&);
};
void foo()
{
A a;
}
========================
bug.cc: In constructor 'A::A(...)':
bug.cc:3: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
This makes the bug a regression as the second code snippet didn't crash
previous compilers.
