"RegisterSecureMemoryCacheCallback" exception in C program

Could someone please explain this error? It craps out when I try to free the array. It works fine when I malloc inside of main so I'm guessing its because of the function scope? I thought if I return the pointer to the malloc then it wouldn't matter where I try to free it.

Thread 1 received signal SIGTRAP, Trace/breakpoint trap.
0x00007ffd80a5719f in ntdll!RtlRegisterSecureMemoryCacheCallback () from C:\Windows\SYSTEM32\ntdll.dll

#include <stdlib.h>
#include <string.h>
#include <stdio.h>

typedef struct array { int length; int size; void *data; } array;

static array* new(int length, int size)
{
    array *array = malloc(sizeof(array));
    array->length = length;
    array->size = size;
    array->data = malloc(length * size);
    return array;
}

int main()
{
    array *a = new(5, sizeof(int));

    free(a->data);
    free(a); // debugger points me to here

    return 0;
}
