my environment:
branch revno: 2998
valgrind-3.5.0
Fedora Core release 6 (Zod)

How to repeat:
valgrind --tool=memcheck --track-origins=yes --leak-check=full -v 
--show-reachable=yes --num-callers=50 ./bin/mysqld --no-defaults 
--skip-grant-tables --skip-name-resolve --basedir=. --datadir=./data

./bin/mysqladmin -uroot shutdown

Probably a duplicate of bug #53947
