Hi and good Easter to all!
I have a = problem using this little function :

unsigned int = Maschera[30];

...
...

void Crea_Mask ( BITMAP *p = )
{
int a, b;

for (a =3D 0; a < p->h; a++)
=     {
    Maschera[a] =3D = 0;
    for (b =3D 0; b < p->w; b++)
=         {
=          if = (p->line[a][b] !=3D 0)
=             {=
=             M= aschera[a] =3D Maschera[a] | (int)pow( (int)2, (int) (p->w - b) = );
=             }=
        }
=     }
}

into a program. After a while it = return a SIGFPE error (I really do not understand why. I used UINT and = *not* float).
Is there anybody who can (and want) help me?

I = tried to debug the program but: using FSDB the system crash on = install_keyboard() allegro function, while from RHGDB it hangs and I = need to reboot (sometimes the system itself reboot!).

As you can = understand, the function take a sprite and create the mask for a pixel = collision detection.
Thank you!
