Details:
WinAVR20071221-
malloc.o and realloc.o in every libc.a is missing the use of SPH when getting
the stack pointer.
This line from malloc.c, which should be getting the SP-
cp = STACK_POINTER() - __malloc_margin;
ends up only getting SPL-
114: 8d b7 in r24, 0x3d ; 61
116: 28 2f mov r18, r24
118: 30 e0 ldi r19, 0x00 ; 0
SPH is not being used.
