can you compile and run this test against a malloc that has the above assertion
activated

#include <stdlib.h>
#include <stdint.h>
#include <stdio.h>
int main()
{
uint64_t* p;
int i;
int n = 8 * 1024;;
if (!(p = malloc(n * sizeof(*p))))
{
fprintf(stderr, "malloc(%d) FAILED\n", n * sizeof(*p));
return 1;
}
for (i = 0; i < n; i++)
p[i] = 0xdeadbeefdeadbeefULL;
free(p);
return 0;
}
