Gundog inflamed compiler (3,6)
I believe the answer is:
red setter
'gundog' is the definition.
(red setter is a kind of gundog)
'inflamed compiler' is the wordplay.
'inflamed' becomes 'red' ('red' can be a synonym of 'inflamed').
'compiler' becomes 'setter' (both can mean a writer of crosswords).
'red'+'setter'='RED SETTER'
(Other definitions for red setter that I've seen before include "Breed of dog" , "description of evening sun?" , "Pet" , "Barker" , "One of my best friends" .)
