Description:
------------
on my linux box fedora core2 with kernel 2.6.5-1.358 i have a segmentation fault on code reported if i compile php with mysql support. if i remove mysql support with --without-mysql all work correctly. on windows 2003 work with both mysql & iodbc support.
this is my configuration: ./configure --with-mysql=/dati/inetpub/mysql --prefix=/dati/inetpub/php --with-gd --enable-gd-native-ttf --enable-sockets --enable-pcntl --without-pear --with-zlib --with-jpeg-dir=/dati/inetpub/src/jpeg-6b --with-curl --with-ttf --with-freetype-dir --with-imap=/dati/inetpub/src/imap-2004a --with-iodbc=/dati/inetpub/iodbc --with-kerberos
Reproduce code:
---------------
<?
putenv("ODBCINI=/etc/odbc.ini");
$db = odbc_connect("myodbc3","root","");
$rec = odbc_exec($db,"select 1");
while(odbc_fetch_row($rec))
echo odbc_result($rec, "1") ."\n";
?>
