- Subject: [PATCH] Fix memory leak in xmlSchemaValidateStream
- When ctxt->schema is NULL, xmlSchemaSAXPlug->xmlSchemaPreRun
- alloc a new schema for ctxt->schema and set vctxt->xsiAssemble
- to 1. Then xmlSchemaVStart->xmlSchemaPreRun initialize
- vctxt->xsiAssemble to 0 again which cause the alloced schema
- can not be freed anymore.
- Found with libFuzzer.
