Description:
The client applications (mysqladmin, mysqltest) generate debug assertions on Windows
machines. These assertions appear as popup windows when running the applications. While a
mere annoyance, it prohibits running the test suite.
When you run the test suite on Windows Vista, the mysqladmin application generates 5-8
assertions. Clicking 'ignore' seems to get one past the problem. However, when the
mysqltest application runs, it generates an endless supply of assertions where clicking
'ignore' does not satisfy the problem.
The assertion is:
Expression: (fh >= 0 && (unsigned)fh < (unsigned)_nhandle)
What this means is the test suite cannot run on Windows Vista.
Interestingly, the mysqltest program does not generate assertions when run on Windows
XP.
Here are stack traces for mysqladmin and mysqltest:

Researching this problem shows that the code in client.c:2050 calls close for a socket
that is not open and is beyond the range of handle values.
How to repeat:
clone mysql-6.0
build on Windows Vista (debug)
run ./mysql-test-run.pl and observe the mayhem ;)
Suggested fix:
Refactor the code in ./sql-common/client.c to not attempt to close the socket if it is
not open.
