Have you run a memory checker (valgrind etc.)? Unless there is compilable code which proves this is a PHP issue this is Not a Bug. As said: For support writing PHP extensions please write the pecl-dev list (pecl-dev at lists.php.net), but that also requires compilable code for useful help. ------------------------------------------------------------------------ [2013-08-24 22:31:38] azq2 at ya dot ru But if use zval - length works ------------------------------------------------------------------------ [2013-08-24 21:58:02] Azq2 at ya dot ru NOT, ITS BUG.

Still 0 would be an unlikely result, but string length handling works in a few hundred other functions flawlessly so it's likely a bug in your code. As this is no support forum please take this somewhere else. (The pecl-dev list might be a good place if you share a bit more code) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
