Bug#57194 group_concat cause crash and/or invalid memory reads with type errors
The problem is caused by bug49487 fix and became visible
after after bug56679 fix.
Items are cleaned up and set to unfixed state after filling derived table.
So we can not rely on item::fixed state in Item_func_group_concat::print
and we can not use 'args' array as items there may be cleaned up.
The fix is always to use orig_args array of items as it
always should contain the correct data.
mysql-test/r/func_gconcat.result:
test case
mysql-test/t/func_gconcat.test:
test case
sql/item_sum.cc:
The fix is always to use orig_args array of items.
