Another ICE with long double, now with optimization only:
$ cat aa.cc
class DataEncoder {
public:
virtual void put_longdouble(long double) = 0;
};
class DataOutputStream {
public:
virtual void write_longdouble(long double value) = 0;
};
class DataOutputStream_impl : virtual public DataOutputStream
{
public:
void write_longdouble(long double value);
private:
DataEncoder *ec;
};
void DataOutputStream_impl::write_longdouble(long double value)
{
ec->put_longdouble(value);
}
$ g++ aa.cc -c -O2
aa.cc: In member function 'void
DataOutputStream_impl::_ZTv0_n12_N21DataOutputStream_impl16write_longdoubleEe(long
double)':
aa.cc:21: internal compiler error: in expand_expr_addr_expr_1, at expr.c:6336
