Yes, definitely. Thanks for letting me know!

Hm, I can't think of any places where we have such a convoluted
structure.

I tried to reproduce this problem using the following test case:

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

  <xsd:complexType name="A">
    <xsd:sequence>
      <xsd:element name="i" type="xsd:int" minOccurs="0"/>
    </xsd:sequence>
  </xsd:complexType>

  <xsd:complexType name="C">
    <xsd:sequence>
      <xsd:element name="a" type="A" minOccurs="0"/>
    </xsd:sequence>
  </xsd:complexType>

  <xsd:element name="root" type="C"/>

</xsd:schema>


#include "test.hxx"

void
f (C const& x)
{
  int i;
  i = x.a ().get ().i ().get ();
}

It does not result in the ICE you observe (xsd-2.1.1, cl.exe 13.10.3077).
Would it be possible for you to provide a small test case that reproduces
the problem?

thanks,
