Bug ID: 115053
Summary: gcc crashed without back trace
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rungecc at gmail dot com
Target Milestone: ---
Minimal example(https://godbolt.org/z/qPKaYdj4o):
```c++
template < typename... Ts >
struct list {};
template < typename... Ts >
constexpr
bool ice = []( list<decltype([](Ts){})...> x = {}) {
return true;
}();
constexpr auto r = ice<int>;
```
GCC just crashes, without any useful diagnostics or internal reports, possibly
runs into an infinite loop when it performs mangling (the crash of clang is
this type).
