The indexer fails on std::abs if the argument is a std::complex type.

#include <algorithm>
#include <cmath>
#include <complex>

int main() {
  float a = 1.0f, b = 2.0f;
  float c = 3.0f, d = 4.0f;

  {
    auto mag1 = std::abs(a);
    auto mag2 = std::abs(b);
    const auto min = std::min(mag1, mag2);
  }

  {
    auto mag1 = std::abs(std::complex(a, b));  // indexer: invalid arguments
    auto mag2 = std::abs(std::complex(c, d));  // indexer: invalid arguments
    auto min = std::min(mag1, mag2);           // indexer: invalid arguments
  }
}
