Seems to happen whenever the length of text equals 1024 characters.
If the limit is set a little higher, compilation fails before reaching the linker.
-----------------
class A(char [] text)
{
    static if (text.length<1023) {
    A!("b"~text) bar() { 
        return null; } // recursive expansion
 }
}

void main()
{
    A!("yyy") b;
}
