Edit report at https://bugs.php.net/bug.php?id=55169&edit=1 ID: 55169 Updated by: pajoye@php.net Reported by: nikic@php.net Summary: mcrypt_create_iv always fails to gather sufficient random data Status: Feedback Type: Bug Package: mcrypt related Operating System: Windows 7 PHP Version: 5.4SVN-2011-07-09 (snap) Block user comment: N Private report: N New Comment: I can't reproduce the problem, are you sure you used the right binaries? c:\test\php540r313114>php -d extension_dir=ext -d extension=php_openssl.dll -r "var_dump(mcrypt_create_iv(1, MCRYPT_DEV_URANDOM));" string(1) "☺" and using NTS: c:\test\php540ntsr313114>php -d extension_dir=ext -d extension=php_openssl.dll - r "var_dump(mcrypt_create_iv(1, MCRYPT_DEV_URANDOM));" string(1) "║" Previous Comments: ------------------------------------------------------------------------ [2011-07-10 14:53:33] nikic@php.net I just tried using an nts instead of a ts build, and it worked there. So it's seems to be some thread safety related problem. ------------------------------------------------------------------------ [2011-07-10 14:32:12] nikic@php.net I'm still seeing the issue in 313114: D:\htdocs\stack>C:\php313114\php.exe -f quick.php Warning: mcrypt_create_iv(): Could not gather sufficient random data in D:\htdoc s\stack\quick.php on line 3 bool(false) ------------------------------------------------------------------------ [2011-07-10 11:32:30] pajoye@php.net yes, 313110 or higher is what you have to test (see the commit in this report, the commits tab). ------------------------------------------------------------------------ [2011-07-10 11:19:34] nikic@php.net Oi, I didn't see your comment, I'm sorry. I will try as soon as a binary is available ;) ------------------------------------------------------------------------ [2011-07-10 11:12:35] nikic@php.net Just tried the snap for 312201, too, and it seems to work there too. Does that mean that either 312202 or 312203 broke it?
