Comment 17 for bug 1028240

Building without --with yassl seems avoids including these functions. With debuginfo installed from:

http://www.percona.com/redir/downloads/Percona-Server-5.1/Percona-Server-5.1.65-14.0/RPM/rhel6/x86_64/Percona-Server-51-debuginfo-5.1.65-rel14.0.475.rhel6.x86_64.rpm:

# nm /usr/lib/debug/usr/lib64/libmysqlclient.so.debug | fgrep ' T ' | fgrep CRYPTO
00000000000bfef0 T CRYPTO_add_lock
00000000000bfee0 T CRYPTO_lock
00000000000bff10 T CRYPTO_mem_ctrl

with http://www.percona.com/redir/downloads/TESTING/Percona-Server-51/Percona-Server-5.1.65-rel14.0/5.1-bug1028240/482/RPM/rhel6/x86_64/Percona-Server-51-debuginfo-5.1.65-rel14.0.482.rhel6.x86_64.rpm:

# nm /usr/lib/debug/usr/lib64/libmysqlclient.so.debug | fgrep ' T ' | fgrep CRYPTO
is empty.

Please try the original issue with these packages. They can be installed from the percona-testing repository as well.
