Not repeatable with maria-5.2, mysql-5.1 . Seems to require views and non-integer field types. Further simplification of the query was not successful.

backtrace:

mysqld: field.cc:3747: virtual int Field_longlong::store(longlong, bool): Assertion `!table || (!table->write_set || bitmap_is_set(table->write_set, field_index) || bitmap_is_set(table->vcol_set, field_index))' failed.
