And here is a testcase that fails also for 4.0.0 and self contained also:
#include <new>
int foo(int n, int *f, long *f1)
{
long t = 0;
*f = 1;
long *fp = new(f) long;
*fp = 1;
for (int i=0; i<n; ++i)
{
t += *fp;
int *b = new (f) int;
*b = i + *f1;
fp = new (f) long;
*fp = t*t;
}
t+=*fp;
return t+*f1;
}
extern "C" void abort ();
int main(void)
{
if (sizeof(int) != sizeof(long)
return 0;
int *a = new int;
long *b = new long;
if (foo(2, a, b) != 6)
abort ();
return 0;
}
