I was experiencing the problem with that piece of DOM project. this is
an abridged version:
class AAA: Object {
public AAA() {
int i = 10;
}
}
class BBB: AAA {
public int j {get; construct;}
public BBB() {
base();
j = 100;
}
}

Right. The construct properties were killing the CG. No way to solve the
issue completely unless we can collect all the values of the construct
properties.
