I wish i could give you more information but it's just this simple configuration and this simple script. As long as i had the UNIQUE index on the INT(15) field the php crashed with access violation within few hours may dependig on load of webpage. I tried to debug by using GFLAGS ON but i can see that the heap crahes always on other adresses (but the debugger has never breaked on buffer overflow). ------------------------------------------------------------------------ [2007-03-20 16:49:29] [EMAIL PROTECTED] I just don't understand what does it have to do with PHP at all - PHP doesn't care if your index is UNIQUE or whether you have an index at all. PHP just passes the query to libmysql. Therefore I suspect either the problem is actually caused by something else or it has nothing to with PHP at all. ------------------------------------------------------------------------ [2007-03-20 16:39:36] donauinsel at hotmail dot com 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. ------------------------------------------------------------------------ [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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
