#25620 [NEW]: Crash / "String is not zero-terminated"

From: xris at farcaster dot net Operating system: GNU/Linux 2.4.20 PHP version: 4.3.3 PHP Bug Type: Reproducible crash Bug description: Crash / "String is not zero-terminated" Description: ------------ I run a rather large PHP System (250k+ LOC). Recently, a number of "Segmentation-Faults" started popping up in my Apache error log. Only some of the PHP pages caused a segfault. These segfaults are mostly reproducible, but could be suppressed by moving code around - like changing order of method definitions, etc. So i set up an identical system as our production server, but with --enable debug. The segfaults did not happen anymore, but i keep getting notices like these: [21-Sep-2003 16:25:34] PHP Warning: String is not zero-terminated (SetVerbandÿƒÌ**rtID' aa) (source: /home/develop/mod_php-4.3.3/Zend/zend_opcode.c:165) in Unknown on line 0 The problem occurres with PHP from at least 4.2.2 to 4.3.3, regardless wether running with Apache 1.3x or Apache 2.0. I would like to provide more information, but i don't know how .. any info on how to trace the reason for this problem would greatly appreciated. Reproduce code: --------------- sorry, i'cant construct a small snippted reproducing this error - it seems to pop up on pages with a large amount of used objects, though (but thats only a guess ..) Expected result: ---------------- well, no php crash? -- Edit bug report at http://bugs.php.net/?id=25620&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25620&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25620&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25620&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25620&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25620&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25620&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25620&r=support Expected behavior: http://bugs.php.net/fix.php?id=25620&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25620&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25620&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25620&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25620&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25620&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25620&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25620&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25620&r=float
