From: ed at supergeek dot com Operating system: Debian GNU/Linux 3.1 (sarge) PHP version: 5.1.4 PHP Bug Type: *Database Functions Bug description: odbc_result w/ IBM DB2 fails trying to allocate huge memory chunk (>500MB)
Description: ------------ PHP 5.1.4 compiled with --with-ibm-db2. IBM DB2 Version 8.2 FixPak 4 (equivalent to Version 8.1 FixPak 11) is installed on machine running Debian GNU/Linux 3.1 (sarge). The IBM DB2 Connect client piece is used to communicate over TCP/IP to a DB2 database running on an AS400 iSeries machine. When odbc_result() is called after simple SELECT statement, the script fails after trying to allocate 544498534 bytes (memory_limit = 500MB). Script seg faults at same location if memory_limit is increased to 600MB. When the same SELECT statement is run using the IBM 'db2' utility on the same client machine, itproduces about 350 records containing a total of less that 350KB of information. The same PHP code that produces this error previously worked under PHP 4.3.4 running on the same machine, but *stopped* working with the same type of error immediately after the iSeries DB2 host machine was upgraded to V5R4. It was this error that prompted the upgrade to PHP5 in the hopes the problem would be solved. No luck! Reproduce code: --------------- Source code unlikely to be useful do to unique nature of our database environment, but can be provided if desired. -- Edit bug report at http://bugs.php.net/?id=37963&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37963&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37963&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37963&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37963&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37963&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37963&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37963&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37963&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37963&r=support Expected behavior: http://bugs.php.net/fix.php?id=37963&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37963&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37963&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37963&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37963&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37963&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37963&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37963&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37963&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37963&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37963&r=mysqlcfg
