Full_Name: Dmitry Bolkhovityanov
Version: 2.4
CVS_Date:
OS: Red Hat Linux 7.1
X_Server: XFree86 4.0.3
Submission from: (NULL) (140.221.9.192)
To reproduce:
1. Start FvwmAnimate
2. Run "FvwmForm FormFvwmAnimate"
3. In the form: set "Effect:" to "Lines", "Iterations:" to "0" and press
[F1-Apply]
4. Try to iconify/deiconify some window and voila -- FvwmAnimate is dead
with strace telling about SIGFPE.
Looks like a trivial division by zero due to lack of checking. A value of
-1 doesn't cause any problems.
Also a value of "-1" for "LineWidth:" causes flickering effect -- seems to
be a line width of 65K.
