The problem is that shutdown function won't execute - EG(timeout) flag should be cleared before execution of shutdown function. I can correct it if you want. ------------------------------------------------------------------------ [2003-07-21 02:07:48] wmeler at wp-sa dot pl I took few days off. You know - holidays. My config.nice : './configure' \ '--disable-all' \ '--with-apxs2=/usr/local/apache2/bin/apxs' \ '--with-config-file-path=/usr/local/apache2/conf/' \ '--enable-debug' \ "$@" my script: <? function shutdown() { echo strlen($GLOBALS['a']); } set_time_limit(1); register_shutdown_function('shutdown'); while (true) $a.='a'; I use apache 2.0.47 with config.nice: "./configure" \ "--enable-so" \ "--with-mpm=worker" \ "$@" Now I have SIGSEGVs instead of hangs :) - probably longjump hit in the middle of emalloc/erealloc and memory cache is corrupted. I used my own module before, witch uses shared variables and locks - thats why it hanged. Now - without my module it just crashes :). ------------------------------------------------------------------------ [2003-07-21 01:30:30] [EMAIL PROTECTED] Still waiting for the configure line.. ------------------------------------------------------------------------ [2003-07-16 01:08:36] [EMAIL PROTECTED] Could you also tell us what configure line you have used? (so we can try to reproduce this too before applying any patches..) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
