File: /tmp/buildd/notify-osd-0.9.33/egg/egg-alpha.c
Function: egg_sine_half_func()
Code snippet:
791 EggFixed sine;

793 timeline = egg_alpha_get_timeline (alpha);
794 frame = egg_timeline_get_current_frame (timeline);
CID 10482 - DIVIDE_BY_ZERO
Assigning: "n_frames" = "egg_timeline_get_n_frames(timeline)".
On this path, function call "egg_timeline_get_n_frames(timeline)" has return value of 0
795 n_frames = egg_timeline_get_n_frames (timeline);
796
CID 10482 - DIVIDE_BY_ZERO
Division by expression "n_frames" which may be zero has undefined behavior
797 x = 512 * frame / n_frames;
798
799 sine = egg_sini (x) * EGG_ALPHA_MAX_ALPHA;
