I changed the pure virtual update() method in QuantLib::Observer
to this to get a breakpoint inside the observer that causes the error:
virtual void update() {
DebugBreak();
}
Here is one quick scenario i got from the debugger when the DebugBreak()
triggered:
- this 0x19ef7398 {observables_=[3]({px=0x19bfd760 pn={...}

The observable at index [2], an Euribor6M IborIndex, has 14 observers.
I assume all of them should be IborCoupons. The observer at index 13 is
recognized only as Observer, which seems odd, and it is also the observer
in which update() fails (this == 0x19ef7398). It seems to me that it is not
a fully constructed/destructed IborCoupon object.
In my final Euribor6M index i expect 21 coupons.
