Using mysql C Api affects memory in my executing program

[Francesco Di Fusco]

Hello, I wrote a Cgi program in C under Linux to read some data to save to a mysql database. Before inserting data in the proper table I show the read data in a table. I noticed something strange. When I display the read data in the table
without connecting to mysql, using these instructions
/* Connect to database */
if (!mysql_real_connect(conn, server, user, password, database, 0, NULL, 0)) {
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
}
the table is diplayed correctly. But if I connect to the database, the connection works correctly, but something strange happens in the table. The last cell displays a dirty value

20 16 0bin" id="82"l

20 is the number of the row, 16 is nhe number of the column, 0 is its value, but bin" id="82"l i do not know what it is
