[xsd-users] Error with sequences using xsd 3.1.x

[Jullien Patrick]

Hi Boris,
 
I have migrated our xsd installation to version 3.1.0, thank you for
your tip on dealing with dates.
 
I'm in front of another problem using sequences, my program stops with a
segfault while calling the sequence_common(const sequence_common&v,
flags f, container *c) when it calls the _clone method.
 
Because of the migration of xsd, I don't know if the bug is mine or not.
Because of the high volume of xsd and source data, I don't what to give
you to point where the problem is...
 
My xsd contains this complex type:

<xs:complexType name="descripDonneesType">
    <xs:sequence>
        <xs:element name="descripEnregistrement"
type="descripEnregistrementType" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
    ...
</xs:complexType>

The complex type descripEnregistrementType is composed like this:

<xs:complexType name="descripEnregistrementType">
    <xs:sequence>
        <xs:element name="descripFormat" type="descripFormatType"/>
        <xs:element name="descripTemporel" type="descripTemporelType"/>
        <xs:element name="descripFrequentiel"
type="descripFrequentielType"/>
        <xs:element name="descripSignaux">
            <xs:complexType>
                <xs:complexContent>
                    <xs:extension base="descripSignauxType">
                        <xs:sequence>
                            <xs:element name="descripSignal"
type="descripSignalType" maxOccurs="unbounded"/>
                        </xs:sequence>
                    </xs:extension>
                </xs:complexContent>
            </xs:complexType>
    </xs:element>
    ...
    <xs:attribute name="pointeurFichier" type="xs:string"
use="optional"/>
    <xs:attribute name="IDEnr" type="xs:unsignedShort" use="required"/>
    <xs:attribute name="typeDonnees" type="EnumTypeDonnees"
use="required"/>
    <xs:attribute name="sousTypeDonnees" type="EnumSousTypeDonnees"
use="required"/>
    <xs:attribute name="nomSAR" type="xs:string" use="optional"/>
</xs:complexType>

The one and only root element is that one:
 
<xs:element name="root_descripDonnees">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="descripDonnees" type="descripDonneesType"
maxOccurs="unbounded"/>
        </xs:sequence>
        <xs:attribute name="version" type="xs:string" use="optional"
fixed="0.79"/>
    </xs:complexType>
</xs:element>
 
The mapping files descripteurDonnees.[ch]xx are generated using cxx with
cxx-tree mode and --generate-ostream --generate-serialization
--root-element-all
 
The descripteurDonnees.cxx contains  a method for getting the
descripEnregistrement_sequence reference:
 
descripDonneesType::descripEnregistrement_sequence&
descripDonneesType::descripEnregistrement()
{
    return this->descripEnregistrement;
}
 
In one of my classes, I try to get the reference like this:
 
descripDonneesType::descripEnregistrement_sequence seqEnr =
m_pDescripDonnees->descripEnregistrement()
 
The m_pDescripDonnees is a valid pointer to an instance of the
descripteurDonnees class (containing true data issued from my data file,
I assume correctly parsed and validated), but this call fails in the
file containers.hxx in the loop over base_const_iterator i(v.v_.begin(),
e(v.v_.end()); i!=e; ++i)
 
Any idea(s) ? Did you ever encoutered such problems ?
 
Cordially,
Patrick
