We are experiencing segmentation faults during export of data. This results in either partial data to be displayed on screen or white screens when using the option to save to file.
We where using php 5.1.6 and phpMyAdmin 184.108.40.206 on Linux
After upgrading the php 5.2.6 and phpMyAdmin 3.1.2 the problem still occurred.
I finally tracked this down to a problem with the mysql_unbuffered_query() function. When changing this function to a normal mysql_query() function in mysql.dbi.lib.php the problem disappeared.
I know this is not really a phpMyAdmin problem, is it not possible to add a setting in the config to switch the use of mysql_unbuffered_query() on and off so other people experiencing this problem can at least still make use of phpMyAdmin?
