Regression: NVCC 11.7 Update 1 fails to compile, works on 11.6

Hi,

I’m bumping my toolchain from CUDA 11.6 to 11.7 Update 1 on Ubuntu 20.04, and the following minimal reproducible example no longer compiles:

#include <type_traits>

template <typename Fn, typename ...Args>
using result_type = typename std::result_of<Fn(Args...)>;

template <typename Fn>
typename result_type<Fn, std::size_t>::type foo(Fn&& fn) {
  return {};
}

int main()
{
  foo([](std::size_t){return 123;});
}


$ /usr/local/cuda-11.7/bin/nvcc -std=c++14 test.cu 
test.cu: In function ‘int main()’:
test.cu:14:37: error: no matching function for call to ‘foo(main()::<lambda(std::size_t)>)’
   14 |   foo([](std::size_t){return 123;});
      |                                     ^

      | ^~~

      |                                   ^

It compiles fine on NVCC 11.6.

This type of code exists pervasively in the RapidCheck testing framework (host code).

Any ideas what could be going on? Thanks!
