Hi all,

Just came across an internal compiler error with avr-gcc 3.3 20030113.  Sorry 
I'm not using a newer version, but I'm attaching a code fragment that 
reproduces the problem, so somebody with a new version can check to see if it 
still exists.  

Here's the output of the error:
address@hidden utos]$ avr-gcc -O2 -Wall -Wstrict-prototypes -fno-builtin 
-mmcu=atmega128 -c bugreport.c
bugreport.c: In function `lcd_set_cgram_ptr':
bugreport.c:94: error: unable to find a register to spill in class 
bugreport.c:94: error: this is the insn:
(insn 81 33 34 2 (nil) (set (mem:QI (plus:HI (reg/f:HI 28 r28)
                (const_int 1 [0x1])) [12 S1 A8])
        (reg:QI 25 r25)) 9 {*movqi} (nil)
bugreport.c:94: internal compiler error: in spill_failure, at reload1.c:1920
