Description
The failure happens in buildbot, see http://buildbot.askmonty.org/buildbot/builders/kvm-fulltest2/builds/1502/steps/test_5/logs/stdio
I could not reproduce it on any other machine where I tried (and I tried several), but it is easily reproducible on the same VM image where the buildbot failure happened. It is an Ubuntu Precise 32-bit VM.
mysqltest_embedded: sql/item_func.h:163: bool Item_func::get_arg0_time(MYSQL_TIME*): Assertion `ltime->time_type != MYSQL_TIMESTAMP_TIME || ltime->day == 0' failed.

Duplicate for MDEV-5374.
After merge of 5374 from 5.3 to 5.5 the problem disappeared.
I believe this is the same problem with:
MDEV-5374main.func_time fails with valgrind warning"Conditional jump or move depends on uninitialised"
in Item_time_typecast::get_date.
It is already fixed in 5.3.
Waiting for Serg to merge 5.3->5.5.
