AVR Freaks

I have been working in a code that was running just  fine, but I had to pause for some days. Today I get back to this very same code and it is broken. I did not changed anything since last time. Looks to me something went wrong with Atmel Studio 7. One thing intriguing me is the RAM data. I did not remember to have more than half of my RAM space taken by this data (see image). Since I´m a kind of newbie in C, is normal all this data from function Init_GSM be in the RAM? I thought the first string would be superposed by the second and so on. Other very suspect behavior (to me) is all the text from strings all over the code, even ones not used yet, shows in the RAM space.

This RAM data looks right to you? Or I did something stupid since the beginning which lead to this now?

void TX_GSM_String (char* String)
{
	for (int i = 0; i < strlen(String); i++)
	{
		while (( UCSR0A & (1<<UDRE0))  == 0){};
		UDR0 = String[i];
	}
}

void Init_GSM (void)
{
	POWERKEY_HIGH;
	_delay_ms(400);						// This start
	POWERKEY_LOW;
	_delay_ms(1200);
	POWERKEY_HIGH;
	TX_GSM_String("AAAA");				//Send 4x "A" to auto baud fix at 9600
	_delay_ms(500);
	TX_GSM_String("ATE0\r\n");			//Echo off OK
	_delay_ms(500);
	TX_GSM_String("AT+CMGF=1\r");		//Set SMS Text mode OK
	_delay_ms(500);
	TX_GSM_String("AT+CNMI=1,2,0,0,0\r");	//Shows contents of new SMS OK
	_delay_ms(500);
	TX_GPS_String("$PSRF103,1,0,0,1*25\r\n");	//Disables GPGLL
	_delay_ms(100);

	_delay_ms(100);
	TX_GPS_String("$PSRF103,3,0,0,1*27\r\n");	//Disables GPGSV
	_delay_ms(100);
	TX_GPS_String("$PSRF103,5,0,0,1*21\r\n");	//Disables GPVTG
	_delay_ms(100);
	TX_GPS_String("$PSRF103,0,0,2,0*20\r\n");	//GPGGA every 10s
	_delay_ms(100);
	TX_GPS_String("$PSRF103,4,0,2,0*24\r\n");	//GPRMC every 10s
