Bug ID: 106925
Summary: internal compiler error: Segmentation fault
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: carlosgalvezp at gmail dot com
Target Milestone: ---
The following minimal example leads to a segfault of GCC on latest trunk:
#include <array>
template <typename T, std::size_t size>
struct MyVector
{
std::array<T, size> data{};
};
template <typename T>
struct Foo final
{
T a{0};
};
constexpr std::size_t kSize = 1;
void foo(MyVector<Foo<float>, kSize> input = MyVector<Foo<float>, kSize>())
{
}
<source>: In instantiation of 'constexpr MyVector<Foo<float>, 1>::MyVector()':
<source>:17:74: required from here
<source>:6:25: internal compiler error: Segmentation fault
6 | std::array<T, size> data{};
