Well, exactly the same code on 1.4.19 parser (aelparse -d -n -w -q
extensions.ael):

[new_test]
exten => _X.,1,Set(~~EXTEN~~=${EXTEN})
exten => _X.,2,Goto(sw-90-${CHANNEL}|10)
exten => _X.,3,NoOp(Finish switch-new_test-90)
exten => _sw-90-.,10,Goto(${~~EXTEN~~}|tests)
exten => sw-90-,10,Goto(sw-90-.|10)

Could it be that you have old version of "aelparse" in system?
However, i think I have seen that "make install" copies it to system.
