I have a weird problem. 
Same code as last night
	if (strcmp("GPVTG",gcBuffer) == 0 )
		{
		gpFieldPtr = (PGM_P) VTG;
		} 

When I look at the disembler and I have
+000019AE:   E461        LDI     R22,0x41         Load immediate
---- No Source
------------------------------------------------------------------------
------------
+000019AF:   E073        LDI     R23,0x03         Load immediate
+000019B0:   ED8C        LDI     R24,0xDC         Load immediate
+000019B1:   E091        LDI     R25,0x01         Load immediate
+000019B2:   940E2119    CALL    0x00002119       Call subroutine
+000019B4:   9700        SBIW    R24,0x00         Subtract immediate
from word
+000019B5:   F431        BRNE    PC+0x07          Branch if not equal

0x0341 is the address of gcBuffer and if I look in the memory view it
has GPVTG
0x01DC should be the address of the compare string. It should be GPVTG
but it has a bunch of unicode strings that read 
Atmega128 configured 0 KT  ETTINGS / Extended Fuse. If you leave out the
0 bytes between each letter.

I looks to be like AVR Studio overwrote some of my data memory. Any
anyone seen this before?

Do I have some kind of incorrect flag on my compiles or do I need to add
one to move the data somewhere?

Or is there something I am supposed to do in AVR Studio 4.1
