Bug ID: 80840
Summary: ICE in convert_nontype_argument reference to double
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: cipherjason at hotmail dot com
Target Milestone: ---
The following code causes an internal compiler error:
#include <iostream>
template <class T, T X>
struct Just;
template <const double& X>
struct Number {
static constexpr double value = X;
using result = Just<const double&, value>;
};
int main() {}
prog.cc:9:45: internal compiler error: in convert_nontype_argument, at
cp/pt.c:6828
using result = Just<const double&, value>;
