#25620 [Opn->Fbk]: Crash / "String is not zero-terminated"

ID: 25620 Updated by: sniper@php.net Reported By: xris at farcaster dot net -Status: Open +Status: Feedback Bug Type: Scripting Engine problem Operating System: GNU/Linux 2.4.20 PHP Version: 4.3.4-dev New Comment: With what PHP version are you getting those valgrind outputs? And are you using the latest valgrind? Previous Comments: ------------------------------------------------------------------------ [2003-09-25 17:45:26] xris at farcaster dot net BTW: i don't know if this might help, but here are two valgrind traces: 1) valgrind --run-libc-freeres=yes ;# SEGFAULT http://farcaster.net/valgrind-err.log 1) valgrind --run-libc-freeres=no ;# NO SEGFAULT http://farcaster.net/valgrind-noerr.log ------------------------------------------------------------------------ [2003-09-25 16:43:59] xris at farcaster dot net > Please provide a short example script which can be used to reproduce this. i'll try- but i fear i'll fast get to a state like [21 Sep 2:50pm EDT] ... isn't there any other way to trace this? possibly using some kind of memory debugger? > And don't mix any Zend extensions in this mess, such as debuggers, optimizers or caches. I didn't mean to; i was just curious about being possibly able to figure out what actually led to this problem. ------------------------------------------------------------------------ [2003-09-25 14:39:45] sniper@php.net Please provide a short example script which can be used to reproduce this. (yes, it's hard, but we can't do anything without it). And don't mix any Zend extensions in this mess, such as debuggers, optimizers or caches. ------------------------------------------------------------------------ [2003-09-25 14:06:05] xris at farcaster dot net I have been too fast declaring my last config was working, as i obviously missed a sideeffect from the DB usage. But I have spent the last two days extensively testing dozens of php builds and now i'm fairly sure i have gotten to a minimalistic config and _still_ being able to reproduce the error (really..): '--prefix=/usr' '--host=i686-pc-linux-gnu' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--datadir=/usr/share' '--sysconfdir=/etc' '--localstatedir=/var/lib' '--disable-all' '--with-pcre-regex' '--without-pear' '--without-gd' '--disable-cgi' '--enable-cli' '--with-mysql=/usr' '--with-mysql-sock=/var/run/mysqld/mysqld.sock' '--with-config-file-path=/etc/php/cli-php4' I'm still getting the same backtrace as in my [22 Sep 3:56pm EDT] post. Using gdb it's segfaulting regardless of having register_globals "on" or "off") - if i just use the CLI from the bash prompt directly, it segfaults only using a "register_globals=on" php.ini ..... ahrgl. BTW: i experimented with using the APD (debugger), strangely enough: when i load the apd extension, the error does not appear, the script works just fine... Maybe its some problem wit the memory management after all (since the error does not seem to be linked to specific extension .. but thats just speculation)? ------------------------------------------------------------------------ [2003-09-23 12:56:45] sniper@php.net Yes, add them one by one..and remember to "rm -f config.cache" always before running configure! ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
