Hi there,

when i was tested main function exiting, all destructor-related were not running.

the GCC attribute is __attribute__((destructor(x))), where x means API priority number.

my local development environment is as follows,

CCS version: 12.7.1.00001

SDK version: 10.0.0.20

and sample code like this,

#include "ti_drivers_open_close.h"
#include "ti_board_open_close.h"

static __attribute__((constructor(101))) void system_entry(void)
{
        System_init();
        Drivers_open();
}

static __attribute__((constructor(102))) void system_entry_2(void)
{
        Debug_LogP("Enter AM64 system.\n");
}

static __attribute__((destructor(101))) void system_exit(void)
{
        Drivers_close();
        System_deinit();
}

static __attribute__((destructor(102))) void system_exit_2(void)
{
        Debug_LogP("Exit AM64 system.\n");
}

when main function was exited, system was gone to exit function and abort function.
