[Bug c++/58457] New: ICE when placement new operator is used with using keyword and custom constructor
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58457
Bug ID: 58457
Summary: ICE when placement new operator is used with using
keyword and custom constructor
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bugzilla.gcc at buszta dot info
Created attachment 30847
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30847&action=edit
Preprocessed source
Minimal reproduction code:
struct allocator
{
void operator delete(void*) {}
void* operator new(unsigned int, void*) {}
};
struct type : public allocator
{
type() {}
using allocator::operator new;
using allocator::operator delete;
};
int main()
{
new (0) type;
return 0;
}
Compiler output:
g++ main.cpp -o main
main.cpp: In function 'int main()':
main.cpp:16:13: internal compiler error: in instantiate_type, at
cp/class.c:7512
new (0) type;
