From: benh at advanceclaims dot com Operating system: Linux PHP version: 4.4.8 PHP Bug Type: PDF related Bug description: A string of unbroken characters wider than width will cause segfault
Description: ------------ pdf_show_boxed() normally wraps lines between words. If a string containing unbroken characters is fed to pdf_show_boxed() such that the unbroken characters render to a width wider than the width value supplied to pdf_show_boxed() it will cause a seg fault because it does not know where/how to wrap the lines. I do realise that pdf_show_boxed() is deprecated and that the problem is almost certain to be with the underlying library. Reproduce code: --------------- $string="A string with a lot of unbroken characters QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQ"; pdf_show_boxed($pdf,$string,$lmargin,$bottom_margin,$width,$height,"left",""); Expected result: ---------------- I would expect pdf_show_boxed to break the string like so: A string with a lot of unbroken characters QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQ QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQ QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQ Actual result: -------------- Segmentation fault -- Edit bug report at http://bugs.php.net/?id=45194&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45194&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45194&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45194&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45194&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45194&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45194&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45194&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45194&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45194&r=support Expected behavior: http://bugs.php.net/fix.php?id=45194&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45194&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45194&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45194&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45194&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45194&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45194&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45194&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45194&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45194&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45194&r=mysqlcfg
