mysql_close segfaults with embedded server. 
(gdb) bt full 
#0  free_embedded_thd (mysql=0x8431228) at lib_sql.cc:482 
	thd = (class THD *) 0x8f8f8f8f

	rc = 1073823776 

How to repeat:
#include <mysql.h> 
#include <stdio.h> 
int main() { 
	int		rc; 
	int i; 
	MYSQL 		*mysql; 
	mysql_server_init(0, NULL, NULL); 
	mysql = mysql_init(NULL); 
	if (mysql_real_connect(mysql, NULL, NULL, NULL, "", 0, NULL, 0) == NULL) { 
	if (mysql_errno(mysql)) { 
		printf("Error 1: %s\n", mysql_error(mysql));

I couldn't reproduce the bug - the example works well on my Linux 8.0
Maybe you should try fresher sources

Thank you for taking the time to report a problem.  Unfortunately
you are not using a current version of the product your reported a
problem with -- the problem might already be fixed. Please download
a new version from http://www.mysql.com/downloads/

If you are able to reproduce the bug with one of the latest versions,
please change the version on this bug report to the version you
tested and change the status back to "Open".  Again, thank you for
your continued support of MySQL.

yes it's fixed now - I tried a bk pull immediatley before I sent the report, but bk replied "nothing 
to pull" (since Friday). Looks like external bk tree should be synchronized more often.
