produce wrong data
By default Item_sp_func::val_str() returns string from it's result_field
internal buffer. When grouping is present Item_copy_string is used to
store SP function result, but it doesn't additionally buffer the result.
When the next record is read, internal buffer is overwritten, due to
this Item_copy_string::val_str() will have wrong data. Thus producing
weird query result.
The Item_func_sp::val_str() now makes a copy of returned value to prevent
occasional corruption.
mysql-test/t/sp.test:
Added test case for bug#13575: SP funcs in select with distinct/group and order by can
produce wrong data
mysql-test/r/sp.result:
Added test case for bug#13575: SP funcs in select with distinct/group and
order by can produce wrong data
sql/item_func.h:
Fixed bug#13575: SP funcs in select with distinct/group and order by can
produce wrong data
The Item_func_sp::val_str() now makes a copy of returned value to prevent
occasinal corruption.
