      Bug#21476: (Thread stack overrun not caught, causing SEGV) · c0ab40d3
      cmiller@zippy.cornsilk.net authored
      The STACK_MIN_SIZE is currently set to 8192, when we actually need 
      (emperically discovered) 9236 bytes to raise an fatal error, on Ubuntu 
      Dapper Drake, libc6 2.3.6-0ubuntu2, Linux kernel 2.6.15-27-686, on x86.
      
      I'm taking that as a new lower bound, plus 100B of wiggle-room for sundry
      word sizes and stack behaviors.
      
      The added test verifies in a cross-platform way that there are no gaps 
      between the space that we think we need and what we actually need to report 
      an error.
      
      DOCUMENTERS:  This also adds "let" to the mysqltest commands that evaluate
      an argument to expand variables therein.  (Only right of the "=", of course.)

      Fixed bug #21493: crash for the second execution of a function · d3d3cef8
      igor@rurik.mysql.com authored
      containing a select statement that uses an aggregating IN subquery.
      Added a parameter to the function fix_prepare_information 
      to restore correctly the having clause for the second execution.
      Saved andor structure of the having conditions at the proper moment
      before any calls of split_sum_func2 that could modify the having structure
      adding new Item_ref objects. (These additions, are produced not with 
      the statement mem_root, but rather with the execution mem_root.)
