Bug ID: 96614
Summary: constexpr deletion failure through pointer to base
with virtual base class
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pkeir at outlook dot com
Target Milestone: ---
Created attachment 49062
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49062&action=edit
A C++ file containing the code described.
The C++20 code below (also attached) fails to compile with GCC trunk.
struct FooBase {
constexpr virtual ~FooBase() {}
};
struct Foo : public FooBase {};
constexpr bool test()
{
FooBase* pb = new Foo;
delete pb;
return true;
}
int main(int argc, char *argv[])
{
static_assert(test());
test(); // no problem
return 0;
}
The error is invoked by the `static_assert` expression, and relates to the call
to `delete pb`. It states:
virtual constexpr Foo::~Foo()’ used before its definition
