Consider this code:

default_minutes:
        addwf   PCL, f                          ; jump table
        retlw   .5
        retlw   .10
        retlw   .15
        retlw   .20

When it was in the beginning of my code, PCL was below 0xff, it
worked. When tidying my code I moved the above to the bottom of the
source, and the code went totally havoc. After 20 minutes of
debugging, I found that two lines before it, PCL overflowed and turned
into 0x00, making the jump-table return a value which made the goto go
to the beginning of the code!

It's easily solvable by moving "default_minutes" to a place near the
top of the source, but is there any way you can solve it in other
ways? I mean, since the chip (16F886) got 8kb program stack, PCL must
be able to keep track of all 8kb data.
