Bug#37284 Crash in Field_string::type()

Browse Source 
The bug is repeatable with latest(1.0.1) InnoDB plugin on Linux, Win,
If MySQL is compiled with valgrind there are errors about
using of uninitialized variable(orig_table).
The fix is to set field->orig_table correct value.


mysql-test/r/innodb_mysql.result:
  test result
mysql-test/t/innodb_mysql.test:
  test case
sql/sql_base.cc:
  set field->orig_table to 'table' value because it may be bogus and
  it leads to crash on Field_string::type() function.
