ranges::min/ranges::max compile error on gcc 8.2 #1076

Closed dutiona closed 5 years ago

dutiona commented 5 years ago

Hello,

I want to report a bug about the function min and max from the library (from range/v3/algorithm). The function min is used in transform2::size_ (l.313) so it is critical when using this view with two ranges.

The repro codes are:

long unsigned int a = 0, b = 1;
auto c = ranges::min(a, b);
long unsigned int a = 0, b = 1;
auto c = ranges::max(a, b);

bug.log.txt

The error I get is joint to the report but the relevant line is:

constexpr T const &operator()(T const &a, T const &b, C pred = C{}, P proj = P{}) const

I noticed that the unit tests for ranges::min/max doesn't cover the use with two arguments.

If, in view/transform.hpp:l313 I replace:

            template<class Self>
            static constexpr size_type_ size_(Self& self)
            {
                return ranges::min(
                     static_cast<size_type_>(ranges::size(self.rng1_)),
                     static_cast<size_type_>(ranges::size(self.rng2_)));
            }

by:

            template<class Self>
            static constexpr size_type_ size_(Self& self)
            {
                return std::min(
                     static_cast<size_type_>(ranges::size(self.rng1_)),
                     static_cast<size_type_>(ranges::size(self.rng2_)));
            }

then it works.

Everything compile with clang though (tested with clang 7.0).

I can't reproduce this (https://godbolt.org/z/L-LhyR). I assume the actual repro is larger, since you suggest that modification of transform.hpp makes the problem go away despite that the repro code doesn't touch transform.hpp.

Hello, I forgot to mention that I'm using the head version of the master branch. I'm not using a tagged version as I need the fix for https://github.com/ericniebler/range-v3/issues/996 . I'm actually trying to migrate and encountered this regresion. I can confirm that with the tagged 0.4.0 version packaged with conan (range-v3/0.4.0@ericniebler/stable) there is no bug.

And yes I narrowed the repro code above (min/max) which is called by transform2 when I perform a to_vector on a transformed2_view.

I narrowed the issue to an incompatibility with the -fconcepts compile option. You can reproduce it on wandbox here: https://wandbox.org/permlink/Z1eprcFWCcAFVBxS

This problem no longer repros for me. Closing.
