After this patch, the assembly generated is much better now. However, it still
contains many optimization problems.
The problem is the code like this.
Let's just walk through the a

Providing more context with the first example (also applies for the rest):
1) // pointer to array - works in clang (trunk),
// works in gcc (trunk)
reinterpret_cast(x);

Do you have a complete disassembly of the function it crashed in and register
dump at the point of crash? That would help.

A test without a lambda that ICEs with -std=c++14 too:
enum E : int { F };
struct X {
E e{F};
};
constexpr X x[1];
auto
foo ()
{
return x[0].e;
}
Note that we don't ICE if the X's member is changed to

--- Comment #2 from Yoshinori Sato ---
Since 0x296318e8 is data, we need to investigate where we jumped.
The backtrace looks normal, so I think you're getting anomalous jumps when
optimizing long_richcompare.

And that also means that this:
enum E : int { F };
struct X {
E e{F};
};
constexpr X x[1]{};
constexpr auto
foo ()
{
return x[0].e;
}
constexpr auto a = foo ();
started to ICE earlier, since r10-6437
