If the problem persists, please give us a _complete_ and short example script which can be used to reproduce this. Also, what was the configure line used to configure PHP? ------------------------------------------------------------------------ [2003-02-06 13:36:56] php at lost dot co dot nz I have already tried to generate the requested backtrace (as already noted below...), but was unable to get apache to segfault while I was watching. I determined the cause of the bug by comparing access and error logs, looking at the called scripts, and examining points of similarity. The bug was confirmed when, after I wrapped the reads to $_SERVER['PATH_INFO'] (see below) the segfault frequency went from 1-200/day to zero. This was the only change made, which would seem to clinch the deal. ------------------------------------------------------------------------ [2003-02-04 16:51:06] sniper@php.net No feedback was provided.
