Apparently for some reason, using the new MySQL v4.x libmysqlclient crashes PHP in both CGI and Apache mode. The problem is fixed by using the bundled library that comes with PHP or using a libmysqlclient prior v4. I haven't been able to establish what exactly causes the crash, since it only happens in phpMyAdmin in sql.php and only when doing 'SELECT' queries. Anything else succeeds. 

I am unable to provide any gdb backtraces or such since I haven't been able to get a usable backtrace, despite my best efforts, but my best guess is that it fails on dlopen() on the mysql library. For some odd reason.

What was the used configure lines for both mysql and php ?
 [2003-04-09 22:34 UTC] cmouse at quakenet dot org 
PHP:
./configure --prefix=/usr --with-apxs=/usr/bin/apxs --enable-inline-optimization --with-mysql=/usr --enable-bcmath --enable-calendar --enable-dba --enable-dbase --enable-dbx --enable-dio --enable-exif --enable-ftp --enable-gd-native-ttf --enable-mime-magic --enable-shmop --enable-sockets --enable-sysvmsg --enable-sysvsem --enable-sysvshm --with-config-file-path=/etc/php4/apache --with-zlib --with-bz2 --with-dom --with-gd=/usr --with-jpeg --with-png-dir=/usr --with-zlib-dir=/usr --with-t1lib=/usr --with-iconv=/usr --with-java=/opt/j2sdk1.4.1_01 --with-ldap=/usr --with-mcal=/usr --with-mcrypt=/usr --with-mhash=/usr --with-recode=/usr --with-mm=/usr --with-gdbm=/usr --with-imap=/usr/src/pine4.53/c-client -with-imap-ssl=/usr/ssl 

MySQL:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --mandir=/usr/share/man --enable-thread-safe-client --enable-assembler --with-pthread --with-libwrap=/usr --with-openssl

Forgot. I used gcc-3.2.2 to compile both of them.

Please be more specific. MySQL 4.x ? that could be MySQL 4.0 or MySQL 4.1 which are totally diffrent.

$ mysql -V
mysql  Ver 12.18 Distrib 4.0.12, for pc-linux (i686)

First of all, get the binary distribution of mysql and try with it. Also try downgrade your gcc to 2.95.x series.
 [2003-04-29 00:23 UTC] cmouse at quakenet dot org 
Ok. Can you explain WHY I should break my system and do all these things you told me to do. I can't use the 'binary distribution' on MySQL due certain system limitations.

Does not crash here -> user error.
