Hi, Sergei!

ha_partition::handle_ordered_index_scan() stores records
in m_ordered_rec_buffer. Then TABLE::update_virtual_fields() updates blob
buffer and frees the old one. Then ha_partition::return_top_record()
returns record from m_ordered_rec_buffer with stale blob pointer. What
should we do with this? I propose to duplicate blob buffer when record gets
into m_ordered_rec_buffer.

More details can be found here:
