85b00b7fb5 Fixed Bug#2479, "dependant subquery with limit crash". 
The problem was that memory was free'd, but it was referenced
later. This free was unneccessary anyway, because join_free() /
JOIN::cleanup takes care of this later on.

Added test case into t/subselect.test for it.

Regards,
Jani

Update after discussion with Monty
 2003-12-12 22:13:57 +04:00
hf@deer.(none)
e6e0937dc4 Proposed fix for #2093 
it happens because of the LEFT JOINT optimization in add_key_part()
This optimization does exactly the same in JOIN and in WHERE conditions 
Not right.
I moved that optimization one level upper.
