The C optimizer may decide that data access operations
through pointer of different type are not related to 
the original data (strict aliasing).
This is what happens in fetch_long_with_conversion(),
when called as part of mysql_stmt_fetch() : it tries 
to check for truncation errors by first storing float
(and other types of data) into a char * buffer and then 
accesses them through a float pointer.
This is done to prevent the effects of excess precision
when using FPU registers.
However the doublestore() macro converts a double pointer
to an union pointer. This violates the strict aliasing rule.
Fixed by making the intermediary variables volatile (
to not re-introduce the excess precision bug) and using
the intermediary value instead of the char * buffer.
Note that there can be loss of precision for both signed
and unsigned 64 bit integers converted to double and back,
so the check must stay there (even for compatibility 
reasons).
Based on the excellent analysis in bug 28400.

we use net->vio in my_net_local_init, but in the my_net_init
implementation we set it after the call, so work with unspecified
net->vio value

expression was evaluated to 0 then the function erroneously returned
the value of the first argument instead of an empty string. 

This problem was introduced by the patch for bug 10963.

The problem has been resolved by a proper modification of the code of
Item_func_substr::val_str.

The Item_func_neg::fix_length_and_dec has been adjusted to

Item_int object whose value is equal to LONGLONG_MIN.

LOCATE(str,NULL) IS NULL erroneously was evaluated to FALSE.

This happened because the Item_func_locate::fix_length_and_dec
method by mistake set the value of the maybe_null flag for 
the function item to 0. In consequence of this the function 
was considered as the one that could not ever return NULL.
