Bug #40144 ctype_collate fails sporadically in pushbuild

Description:
Sporadic pushbuild failure in all 6.0 trees on vm-win2003-64-b, started 2008-07-31:

main.ctype_collate             [ fail ]

mysqltest: At line 11: query 'CREATE TABLE t2 (
latin1_f CHAR(32) CHARACTER SET latin1 COLLATE koi8r_general_ci NOT NULL
)' failed with wrong errno 2013: 'Lost connection to MySQL server during query', instead of 1253...

The result from queries just before the failure was:
DROP TABLE IF EXISTS t1;
DROP TABLE IF EXISTS t2;
CREATE TABLE t1 (
latin1_f CHAR(32) CHARACTER SET latin1 NOT NULL
);
CREATE TABLE t2 (
latin1_f CHAR(32) CHARACTER SET latin1 COLLATE koi8r_general_ci NOT NULL
);
ERROR HY000: Lost connection to MySQL server during query

More results from queries before failure can be found in e:\var-n_mix-100\log\ctype_collate.log
