Bug ID: 65728
Summary: template instantiation complains of sizeof failing due
to incomplete definition
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ron at vaniwaarden dot org
Following code fails to compile in 4.8.2, complaining about an incomplete
definition. Definition is complete and it also compiled in 4.2.1 but also
fails in 4.6.3:
#include <cstdlib>
struct S
{
void method(){}
};
template<size_t sz, size_t tot>
class genpool
{
};
template <class T>
class mempool
{
private:
genpool<sizeof(T), 10*sizeof(T)> p;
};
template <class obj, class mthd>
class functor
{
private:
obj& o;
mthd m;
static mempool<functor<obj, mthd> > pool;
};
template <class obj, class mthd>
mempool<functor<obj, mthd> > functor<obj, mthd>::pool;
int main()
{
typedef void (S::*m)();
typedef functor<S, m> fctr;
fctr f;
}

Not a bug. Recursive template although I don't know why this is a problem
because the recursion occurs in a static data member that does not contribute
to the size.
