Description:
4.1 not affected.
When I run ./mysql-test-run t/information_schema*.test t/init_connect.test,
I often get, in init_connect:
*** glibc detected *** /m/mysql-5.0-wl1012/client/.libs/mysqltest: double free or corruption (out): 0x00000000005f4ff0 ***

in previous post, please ignore the "-wl1012" string, I later got the same failure in a clean 5.0 tree.
