Description:
A server compiled with yassl on windows will crash when one of the SSL related functions are used. This problem only appears in 5.1, works fine in 5.0

ssl                            [ fail ]

Errors are (from C:/cygwin/home/mysqldev/pb/mysql-5.1-new/push-andrey@lmy004.-20060317122145.info/mysql-5.1.8-beta-standard/mysql-test/var-n_stm-5/log/mysqltest-time) :
mysqltest: At line 9: query 'SHOW STATUS LIKE 'Ssl_cipher'' failed: 2013: Lost connection to MySQL server during query
(the last lines may be the most important ones)

How to repeat:
Compile on windows and run ./mysql-test-run.pl -do-test=ssl

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

I don't like truncating a the SSL list silently, so I suggest adding a DBUG notice about an incomplete list when the buffer is filled before the SSL-info list is exhausted.

I don't especially want to restructure the code so that we can resize the buffer to accommodate all the data, but I don't have a suggestion about how to represent the data to the user that some information isn't shown.

Pushed a fix to 5.1.8 that protects against buffer overrun in 'show_ssl_get_cipher_list' that caused the server to crash when a SHOW STATUS was called on a server linked with yaSSL.

Thank you for your bug report. This issue has been committed to our
source repository of that product and will be incorporated into the
next release.

If necessary, you can access the source repository and build the latest
available version, including the bugfix, yourself. More information
