Description:
Several test cases cause mysqltest to crash when run with --embedded-server --ps-protocol: cache_innodb func_misc innodb_mysql query_cache query_cache_merge view_query_cache

The tests pass with --embedded-server, and with --ps-protocol, but not with both at the same time.

How to repeat:
Built with BUILD/compile-pentium-debug-max on Linux.

$ ./mtr --embedded-server --ps-protocol cache_innodb
Requesting build thread... got 200
Logging: ./mtr --embedded-server --ps-protocol cache_innodb
MySQL Version 5.1.22
<cut>
main.cache_innodb              [ fail ]

ERROR: mysqltest returned unexpected code 139, it has probably crashed

Aborting: main.cache_innodb failed in embedded ps-protocol mode. To continue, re-run with '--force'.

Suggested fix:
Unfortunately I don't see anything helpful in var/log/*, and the --gdb option doesn't work with --embedded-server.  I didn't investigate futher to see where it's crashing.

  PS-protocol data is stored in different format - the MYSQL_RECORDS->data
  contains the link to the record content, not to array of the links to
  the field's contents. So we have to handle it separately for
  embedded-server query cache.

Noted in 5.1.23, 6.0.5 changelogs.

With libmysqld, use of prepared statements and the query cache at the
same time caused problems.
