; This label will conflict with the reloc on the next line.
; TODO(rogerm): The symbols generated from assembly don't seem expressive
;     enough to generate both data and code labels, so this isn't quite
;     reproductive of the label/reloc collision we saw in chrome 17.0.963.12
;     (where we were notified of a data symbol, a reloc, and two code labels
;     all referring to the same address), but it does trigger the same check.
;     More troubling is the case table below, for which we get no data symbol
;     from the assembly driven debug info, we just get a code label. This
;     causes that label to be interpreted as code.
