-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.
