           Summary: requires expression with lambda fails
           Product: gcc
           Version: 11.2.1
            Status: UNCONFIRMED

constexpr bool test = requires { [](auto o){}(0); };
static_assert(test);
---

gives

<source>:1:37: error: expected primary-expression before 'auto'
    1 | constexpr bool test = requires { [](auto o){}(0); };

msvc fails that condition, clang compiles ok.
