Bug #10714 Inserting double value into utf8 column crashes server

Description:
Inserting a double value into a utf8 column crashes mysqld.

Crashes under Windows; cannot repeat in Linux.

How to repeat:
DROP TABLE IF EXISTS t1;
CREATE TABLE t1 ( a VARCHAR(255) ) DEFAULT CHARSET utf8;
INSERT INTO t1 VALUES ( 1.0 );

Suggested fix:
n/a

Does not crash on my FreeBSD box.  Also, I found a strange fact:
on my FreeBSD box (unlike Windows), execusions follows through
Item_real::save_in_field(), not through Item_int::save_in_field().
