You can access the patch from: http://lists.mysql.com/commits/102937 3123 Konstantin Osipov 2010-03-10 A fix for Bug#49972 "Crash in prepared statements": The problem is introduced by WL#4435 "Support OUT-parameters in prepared statements". When a statement that has out parameters was reprepared, the reprepare request error was ignored, and an attempt to send out parameters to the client was made. Since the out parameter list was not initialized in case of an error, this attempt led to a crash. Don't try to send out parameters to the client if an error occurred in statement execution. @ sql/sql_prepare.cc Don't try to send out parameters if error. @ tests/mysql_client_test.c Re-enable the test case for Bug#49972.

Noted in 6.0.14 changelog. If an error occurred when a prepared statement was reprepared, OUT parameters incorrectly could be sent to the client, leading to a crash. No 5.5.x changelog entry because this error appears in no 5.5.x release.
