Crash in the schema validator
Summary: Crash in the schema validator
Product: Xerces-C++
Version: 2.1.0
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: Normal
Priority: Other
Component: Validating Parser (Schema) (Xerces 1.5 or up only)
AssignedTo: xerces-c-dev@xml.apache.org
ReportedBy: alby@exceloncorp.com
When validating a file using the schema at
http://www.w3.org/MarkUp/Forms/2002/XForms-Schema.xsd using a SAXParser
prepared with setExitOnFirstFatalError(false), setDoValidation(true),
setDoNamespaces(true), setDoSchema(true) and setValidationSchemaFullChecking
(true), the validator crashes inside UnionDatatypeValidator::isSubstitutableBy
because the fMemberTypeValidators is NULL.
A simple fix for this problem is the following patch:
cvs diff -u UnionDatatypeValidator.hpp
Index: UnionDatatypeValidator.hpp
