+Subject: [PATCH] Propagate allocation failure from ogg_sync_buffer.
+
+Instead of segfault, report OP_EFAULT if ogg_sync_buffer returns
+a null pointer. This allows more graceful recovery by the caller
+in the unlikely event of a fallible ogg_malloc call.
+
+We do check the return value elsewhere in the code, so the new
+checks make the code more consistent.
+
+Thanks to https://github.com/xiph/opusfile/issues/36 for reporting.
