#39802 [NEW]: PHP segfaults with odbc_connect()

From: webmaster at guestwho dot com Operating system: FreeBSD 6.1-RELEASE PHP version: 5.2.0 PHP Bug Type: ODBC related Bug description: PHP segfaults with odbc_connect() Description: ------------ I have been trying to connect a microsoft access database using PHP, mdbtools and unixODBC, but any attempt at calling odbc_connect() results in an immediate segfault. This behaviour occurs in both the shared apache module and the standalone cgi version. Only the latter dumps core though. PHP is configured as follows: ./configure --with-apxs2=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql \ --with-zlib --with-pdo-mysql=/usr/local/mysql --enable-mbstring \ --with-curl=/usr/local --enable-debug --with-openssl=/usr/local/ssl \ --with-gd --with-custom-odbc=/usr/local Here are the unixODBC configs: odbcinst.ini ------------- [MDBToolsODBC] Description = MDB Tools ODBC drivers Driver = /usr/local/lib/libmdbodbc.0 Setup = FileUsage = 1 CPTimeout = CPReuse = DisableGetFunctions = 0 UsageCount = 1 -------------- odbc.ini -------------- [Water] Description = Water Module Driver = MDBToolsODBC Trace = Yes TraceFile = /var/log/sql.log Database = /home/skeleton-man/public_html/water/water.mdb Servername = localhost UserName = Password = --------------- Reproduce code: --------------- <? $myDB = odbc_connect('Water','',''); $query = "SELECT RLCode FROM Account"; $result = odbc_exec($myDB, $query); while (odbc_fetch_row($result)){ print odbc_result($result,'RLCode')."<br>"; } ?> Expected result: ---------------- It should print a list of account numbers from the RLCode column in the database. Actual result: -------------- PHP segfaults immediately with no output.
