DATA opnames<1>+116(SB)/4,$string<1>+739(SB)

and

DATA etnames<1)+72(SB)/4,$string<1>+912(SB)

are the second initializations of both opnames and etnames.

you can grep for them in the output of

8c -S source.c

that's all i can help, cause i can't tell what $string<1>+739(SB) and $string<1>+912(SB) refer to

since they are adresses.

> int num = 30;

Looks easy to fix, but I understand where you're coming from. What
stops you from using a workaround?
