Mplab error -CORE-W0016: Halted due to PC incrementing over the Maximum PC address

[eng_rania]

I use MPLAB IDE V8.30 ( Debugger: MPLAB SIM, Compiler: PICC-18_pro_9.61 ),
I write a small program (for PIC18F4420) just turn on/off leds while using a simple delay function, it compiles fine with Build Succeeded, but the following error occurred when I tried to debug the program " CORE-W0016: Halted due to PC incrementing over the Maximum PC address and wrapping back to Zero " I don't know if there is certain setting causes this problem, Any help will be highly appreciated.

core w0016 problem

It is always helpful if we can see your program .

out of scope mplab

It is always helpful if we can see your program .

thank you for your concern,
note that
**i have a problem in tracing the updated values of the int i & j as it appears "out of scope" in the watch window,
** by viewing the program memory, i found that an instruction of goto-- is performed although it is not included in the code, it causes the unexpected jump to a far place in the program memory?????

this is the program:
#include <htc.h>

void Delay2Sec (void);

void main (void)
{
__CONFIG(1, HSPLL);
SBOREN = 0; //deactivate power out reset
TRISA = 0x00; //assign RAs as output pins, for testing leds
//(osc pins read as 0's)
TRISE = 0x00; //assign REs as output pins, for testing leds
TRISC = 0x00; //assign RCs as output pins, for testing leds
ADCON1 = 0x0F; //all channels digital
PORTA = 0x00;
PORTE = 0x00;
PORTC = 0x00;

while (1) {
Delay2Sec ();
RA1 = 1;
RA2 = 1;
Delay2Sec ();
RA3 = 1;
RA4 = 1;
Delay2Sec ();
RA5 = 1;
RE0 = 1;
Delay2Sec ();
RE1 = 1;
RE2 = 1;
Delay2Sec ();
RC0 = 1;
RC1 = 1;
Delay2Sec ();
RA1 = 0;
RA2 = 0;
Delay2Sec ();
RA3 = 0;
RA4 = 0;
Delay2Sec ();
RA5 = 0;
RE0 = 0;
Delay2Sec ();
RE1 = 0;
RE2 = 0;
Delay2Sec ();
RC0 = 0;
RC1 = 0;
}
}

void Delay2Sec (void) //delay about 0.5 sec for (10 MHz crystal, HSPLL mode)
{
//locals
unsigned int i = 0;
unsigned int j = 0;

for (i=0; i<10; i++)
for (j=0; j<670; j++);
}
