Re: PHP 4.0 Bug #6709 Updated: intermittent segmentation faults

I managed to narrow the problem down to the use of --enable-trans-sid The problem occured when PHP 4.01 or 4.02 were compiled with ./configure --with-mysql --with-apache=../apache_1.3.x --enable-track-vars - -enable-trans-sid It was occuring at random with any script that produced HREFs. A re-compile without the above --enable-trans-sid cured the problem. P.S.
