This code will compile to rather large object and executable files.

module test;

class lookup(uint N)
{
    real[N] items;
}

void main()
{
    lookup!(1000000) test;
    test = new typeof(test)();
}

System: XP/SP DMD 0.94

The file size is a function of what value lookup is instantiated with, i.e. a higher number will increase file size.

This bug is funny. :-)
