Whenever an unsigned integer multiply a float or a double, it will
crash my Amiga 1000, but the same source code works fine on a PC or
UNIX machine. This is painful, because you can be careful by type
casting, but when you compile a PD program, especially the big files
you cannot afford the time to find them. I use Lattice C compiler 5.05,
I wonder if this is a bug, whether 5.10 have the same problem. Can
any body kindly take the risk of crashing, and try the following:

#include <stdio.h>
main()
{
    unsigned int i;
    int j;
    float a;
    i = 10;
    j = 10;
    a = j*15.0;             /* should not crash here */
    printf("a= %f:n",a);
    a = i*15.0;             /* crash here on my machine*/
    printf("a= %f:n",a);
}

/* end of the program */
