Bug ID: 115007
Summary: [modules] ICE in maybe_clone_body when calling virtual
destructor from instantiated template
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nshead at gcc dot gnu.org
Blocks: 103524
Target Milestone: ---
The following sample ICEs on trunk:
// a.cpp
module;
struct S {
virtual ~S() = default;
virtual void f() = 0;
};
module M:a;
S *p;
template <typename T> void format(T) { p->~S(); }
template void format(int);
// m.cpp
export module M;
import :a;
'g++ -fmodules-ts -Wno-global-module -S a.cpp m.cpp' results in:
m.cpp: In destructor ‘S@M:a::~S()’:
m.cpp:2:11: internal compiler error: Segmentation fault
2 | import :a;
