From: Operating system: Linux PHP version: 5.4.0 Package: Readline related Bug Type: Bug Bug description:when using readline_info to set line_buffer, it causes memory corruption
Description: ------------ Using the function readline_info to set the property "line_buffer" performs a direct setting of readline rl_line_buffer. It works for short lived scripts but for longer ones, they start to crash randomly with sig violations. The proper way for libreadline is to use rl_replace_line to set the line buffer. In addition, readline_info does not allow you to set "point" and "end" properties that are needed when changing line_buffer. I've included a patch that fixes the setting of "line_buffer" and adds the ability to set both "point" and "end" properties. Test script: --------------- None. Random crashes. Expected result: ---------------- None. Actual result: -------------- None. -- Edit bug report at https://bugs.php.net/bug.php?id=61584&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61584&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61584&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61584&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61584&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61584&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61584&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61584&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61584&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61584&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61584&r=support Expected behavior: https://bugs.php.net/fix.php?id=61584&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61584&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61584&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61584&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61584&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61584&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61584&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61584&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61584&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61584&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61584&r=mysqlcfg
