           Summary: crash on invariant struct member function referencing
                    globals

When an invariant member function of an invariant struct uses global or static
member variables, the compiler crashes. This happens only when this function is
invoked more than once. See the code below.

int bar;

struct Foo
{
    invariant int func()
    {
        return bar;
    }
}

void main()
{
    invariant(Foo) foo;
    printf("%d", foo.func());

    /* uncomment this line and the compiler aborts with:
       Assertion failure: 'ito->isInvariant()' on line 335 in file 'mtype.c'
    */
    //printf("%d", foo.func());
}
