Boost 1.58.0 has a workaround by making one function "explicit".

Are there any news on this bug? At least for us, this keeps production code
from being able to work with any boost >1.55, which is becoming an increasingly
bigger issue.

Ever so little simplified:

_Tp declval();

static A __test(int);
typedef decltype(__test<_From, _To>(0))

Or a bit more compact and obfuscated:
template
struct A {
static constexpr _Tp value = 0;
};
template
struct B;
template
struct B<_B1> : _B1 {};
template
_Tp declval();

struct C {

This is what C-reduce came up with:
markus@x4 ~ % cat boost.ii
template
struct integral_constant {
static constexpr _Tp value = 0;
};
template
struct __and_;
template
struct __and_<_B1> : _B1 {};

I wanted to, but the problem is that the ii file is 2.7MB, more than the
maximum allowed file size of 1000KB. Should I upload it to a different site?
Also I just realized that the problem only occurs

You should have read https://gcc.gnu.org/bugs/ and attached preprocessed code
anyway, not everyone has Boost 1.56 already installed.
