------- Comment #3 from rguenth at gcc dot gnu dot org 2008-10-02 14:10 -------
Confirmed. Reduced testcase:
struct QListData {
struct Data {
int ref;
int alloc, begin, end;
void *array[1];
};
Data *d;
inline void **at(int i) const { return d->array + d->begin + i; }
};
template <typename T> class QList {
struct Node {
void *v;
inline T &t() { return *reinterpret_cast<T*>(this); }
};
union {
QListData p;
QListData::Data *d;
};
public:
T &operator[](int i) {
if (d->ref != 1)
detach_helper();
return reinterpret_cast<Node *>(p.at(i))->t();
}
void insert(int i, const T &t);
void detach_helper();
};
class QPoint {
int xp;
int yp;
};
QList<QPoint> pieceLocations;
void mousePressEvent(int found)
{
QPoint location = pieceLocations[found];
pieceLocations.insert(found, location);
}
somebody looks up an ARRAY_REF from the nary op table. Which usually happens
with invalid gimple. But I have to check further.
