Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

create buffer
----cut----
$abc{'fish'}
def
ghi
----cut----
narrow-to-region
----cut----
def
----cut----
position to end of buffer
type $ a b M-/ SPC M-/

does not expand as it will when buffer is widened
AND
message "dabbrev-expand: Args out of range: 5, 17"
is received (diff numbers possibly)

HERE's MY THINKING.
the remainder of the buffer is like unto another buffer
which dabbrev-expand does search.

HERE's MY USE:

narrowed to function for editing but wish to dynabbrev
various variables etc. and it doesn't work.
