If gct is declared as a double instead of var it works

Still up.
A standalone example replicating the error follows

#include "gridtools/clang_dsl.hpp"
using namespace gridtools::clang;

stencil_function myFun {
  storage first, second;
  Do() { return first * second; }
};

stencil teststencil {
  storage in_field, out_field;
  void Do() {
    vertical_region(k_start, k_end) {
      double q = 3.0;
      var myVar = myFun(in_field, out_field) * q;
      out_field = out_field * myVar;
    }
  }
};

If the initialization is substituted with an assignment, the problem seems to disappear:

var myVar;
      myVar = myFun(in_field, out_field) * q;

But as soon as instead of var we use double, the following assert triggers:

Assertion failed: `LHSAccessIDs.size() == 1' left hand side should only have only one AccessID
Function: 'dawn::PassFieldVersioning::RCKind dawn::PassFieldVersioning::fixRaceCondition(std::shared_ptr<dawn::iir::StencilInstantiation>, const dawn::iir::DependencyGraphAccesses*, dawn::iir::Stencil&, dawn::iir::DoMethod&, dawn::iir::LoopOrderKind, int, int)'

from dawn.
