[SOLVED] EDivByZero when mouse move in window (custom gui binding)

[kieski]

Hello,
I tried to make a FPC binding for the IUP gui toolkit. It is working well, if you don't mind the fact that moving the mouse inside the window makes it crash.
The program throw a SIGFPE, EDivByZero: Division by zero and  Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged. (apparently it isn't revelant)

Clicking on buttons to open another dialog is ok.
The same program in C doesn't crash.

I compiled myself the library and there was no error;
FPC returns no error nor warnings at compilation.

Do you have any idea about this ? I searched but found nothing about this behavior.

Here are the units and the program just in case :

Call Math.SetExceptionMask with exZeroDivide in one of the set elements. C doesn't set any mask by default, FPC sets according to platform.

Thanks, it works now!
