ID: 40855 User updated by: donauinsel at hotmail dot com Reported By: donauinsel at hotmail dot com -Status: Feedback +Status: Open Bug Type: Reproducible crash Operating System: W2K PHP Version: 5.2.1 New Comment:
It's reproduceable on windows (ISAPI) - that's all. If you run it as CGI it may never happen ?! I have no linux at all here to test neither than other OS'es. I reported to mysql because may the result given back to php is wrong. Sorry for crossposting. If you're sure that it's not bug but a feature then close this please but i'm pretty sure that other people on the WWW have similar crashes and if UNIQUE index is corrupting the heap under these circumstances may i can help with this simple tip to check. Previous Comments: ------------------------------------------------------------------------ [2007-03-20 16:02:57] [EMAIL PROTECTED] Not reproducible on Linux. Also, I don't undrestand - why did you report it BOTH to MySQL people and here? Are you able to replicate it on another machine? Another OS? Linux and valgrind would most likely give some more information, not just a random backtrace. ------------------------------------------------------------------------ [2007-03-20 07:48:08] donauinsel at hotmail dot com Btw. The stacktrace does not help in this case because it always happens on other adresses so the heap corruption is the error not the error itself. ------------------------------------------------------------------------ [2007-03-19 19:07:27] donauinsel at hotmail dot com I tried to debug but heap always crahes on other circumstances. The old windbg reported eg.

To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2007-03-19 16:03:01] donauinsel at hotmail dot com Description: ------------ I repoted this bug to mysql but affect PHP system so may the ISAPI or zend engine cannot handle -> result is a heap crash. Reproduce code: --------------- Set UNIQUE index on any mysql database INT(15) field and insert same time stamps multiple times. After doing this for few hours the heap will crash as rersult. http://bugs.mysql.com/bug.php?id=27237 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40855&edit=1
