Bug ID: 117273
Summary: internal compiler error: Segmentation fault at
extend_ref_init_temps(tree_node*, tree_node*,
vec<tree_node*, va_gc, vl_embed>**, tree_node**)
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: yihan4845 at gmail dot com
Target Milestone: ---
Compiler Explorer: https://godbolt.org/z/dfdsq58Yd
The following program:
```
namespace std {
typedef __SIZE_TYPE__ size_t;
template<typename T> struct initializer_list {
const T *p; size_t n;
const T *p, size_t n;
};
}
struct C { std::initializer_list<int> a; };
C c = {};
```
will trigger segmentation fault for gcc trunk.
