Valgrind Memory Leak in QXmlSchema (5.9.1)

XMLWordPrintable

    • 3b5a20dc02bd00032a19c2951bfa940e6d83aca0

      I've found a memory leak in QXmlSchema.

      It's easily reproductible using Qt's Xml Schema Validation Example.

      $ valgrind --tool=memcheck --leak-check=full ./schema

schema.load(schemaData);
