While reducing this bug I found an unrelated to this source bug 30917 so I have
to rereduce this.

Reduced testcase:
struct QString { ~QString(); };
template <class T> struct QValueListNode {
QValueListNode<T>* next;
T data;
};
template <class T> struct QValueListPrivate
{
~QValueListPrivate()
{
QValueListNode<T>* p = node->next;
while( p != node )
{
QValueListNode<T>* x = p->next;
delete p;
p = x;
}
}
QValueListNode<T>* node;
};
struct Option { QString sarg; };
struct Options {
QString helptext;
QValueListPrivate <QString> filelist;
QValueListPrivate <Option> optlist;
};
Options options;

------- Comment #5 from wouter dot vermaelen at pi dot be 2007-03-19 10:55 -------
I hit the same problem. My testcase is slightly shorter, but i'm not sure it's
also actually simpler. Requires -O -finline-functions
> cat bug.ii
struct S {
S();
~S() {}
void f();
};
void f() {
int x, y;
while (x) {
x = x ? x : y;
}
}
void g() {
S s;
s.f();
}
void h() {
S s;
f();
g();
}
> g++ -O -finline-functions bug.ii
bug.ii: In function 'void h()':
bug.ii:16: internal compiler error: in alloc_aux_for_block, at cfg.c:665
