I have problems with php5-recode and php5-odbc. With both packages installed, odbc_execute() hangs up causing Segmentation Fault. I was using a simple script to test that:
#DSN "mydb" with a user and password "marin"
$connect = odbc_connect("myaccess", "", "");
# query the users table for name and surname
$query = "SELECT * FROM FRT_NAME";
# perform the query
$result = odbc_exec($connect, $query);
# fetch the data from the database
$name = odbc_result($result, 2);
# close the connection
After uninstalling php5-recode, the issue is solved.
