3466  * DO_JUMP overwrites the "obj" variable of the loop and sets it to the target
3467  * (i.e. the corresponding ELSE or ENDIF). After that, processing for the given

3469  * regularly, "obj" is being updated to point to obj->next, so object parsing
3470  * continues right after the corresponding ELSE or ENDIF. This means that if we
3471  * find an ELSE, it's corresponding IF must not have jumped, so we need to jump
