It appears that the label for a continue statement is null. At least it is not being printed with --verbose. Need to also check that the continue statement action is not called twice. Or perhaps it is being called twice because there are two loops.
Code to reproduce the bug follows:
DO 1620 J = K1, N
DO 1620 I = J, N
A = I
1620 CONTINUE
end
This is the same bug as 3133821 which I have closed. Text from 3133821:
In some instances, the location of the label token is not specified.
This is an incorrect one: R 313:label: lbl=[@-1,0:0='1620',<10>,0:-1]
This is a correct one: R 313:label: lbl=[@65,74:77='1620',<10>,4:0]
Code illustrating bug
-------------------------------------
DO 1620 J = K1, N
DO 1620 I = J, N
A = I
1620 CONTINUE
end
