599eb0dc86 Fixed MDEV-5724 "Server crashes on SQL select containing more group by and left join statements using innodb tables" 
The problem was that a big record was allocated on the stack, which casued stack to run out.
  
Fixed by using my_safe_alloca() instead of my_alloca() when allocating records.
Now only records <= 16384 are allocated on the stack.

  Added test case
