Bug ID: 96064
Summary: Defaulted constexpr spaceship operator triggers
internal compiler error after including utility
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: milasudril at gmail dot com
Target Milestone: ---
The following code crashes gcc-10.1
#include <utility>
class WrappedValue
{
public:
constexpr explicit WrappedValue(double val): m_value{val}{}
constexpr bool operator<=>(WrappedValue const&) const = default
constexpr double value() const
{return m_value; }
private:
double m_value;
};
Any of the following actions prevents the crash:
* Remove `#include <utility>`
* Make `operator<=>` non-constexpr
* Make `operator<=>` non-defaulted
Error log:
<source>: In member function 'constexpr bool WrappedValue::operator<=>(const
WrappedValue&) const':
<source>:8:24: internal compiler error: Segmentation fault
8 | constexpr bool operator<=>(WrappedValue const&) const =
default;
| ^~~~~~~~
