Summary: SIGABRT with simple array or struct access

Initial Comment:
try...

volatile int x[2] = { 4,5 };

void main(void) {
//  volatile int hope;  // okay
	int hope;			// not okay
	hope = x[1];
}

then...

sdcc -mpic16 -p18f8620 test2.c
pic16_aopOp:1302 called for a spillLocation -- assigning WREG instead 
--- CHECK!
gen.c:1304: failed assertion `getSize(sym->type) <= 1'
Caught signal 6: SIGABRT

sdcc -v

ds400/hc08 2.5.6 # (May 18 2006) (UNIX) 

same error with this...

typedef struct { 
	int A; 
	int B; 
} my_t; 

volatile my_t foo = { 1,2 };

void main(void) {
//  volatile int hope;  // okay
	int hope;			// not okay
	hope = foo.A;
}

If hope is volatile then this compiles. Implies that cause is linked to 
optimisation.
