ac_int tracing; getting runtime exception

[sa425316543]

Hi,
I am getting a runtime exception when I try to trace the ac_type signal. I really appreciate if I could get some assistance or examples of tracing using the ac_types used in systemC context.

SystemC version: 2.3.3
ac_types version: 4.6.1
Compilers tried : MSVC 2019, gcc 9.3.0

#include "systemc.h"
#include "ac_int.h"
#include "ac_sc.h"

int sc_main(int argc, char *argv[])
{
std::cout << "Starting DUT Simulation\n";
// Open VCD file
sc_trace_file *trace_file = sc_create_vcd_trace_file("test");

ac_int<14, false> ac_test;
sc_uint<14> sc_test;

ac_test = 10;
sc_test = 10;

sc_trace(trace_file, ac_test, "test.ac_test"); // exception goes away if I comment this line.
sc_trace(trace_file, sc_test, "test.sc_test");

sc_start(10, SC_NS);
sc_close_vcd_trace_file(trace_file);

std::cout << "SIM Complete";
return 0;

}

Here is the exception:
Exception thrown at 0x00007FF666D15972 in ac_type_tests.exe: 0xC0000005: Access violation writing location 0x0000000000000000.
