Session exceptions

Hello I have run into some problems in my session handler which I am having a hard time figuring out. I do the following in my read function: PS_READ_FUNC(riak) …. RIAK_CALL_METHOD2(RiakBucket, get, zoutput, data->zbucket, zkey, data->zgetprops); if (EG(exception)) { // HANDLE This works fine unless session autostart is turned on, then the if is never reached if an exception is thrown, instead you get an Unhandled exception immediately I think tracked it down to this: in the zend_throw_exception_internal function in zend_exception.c if (!EG(current_execute_data)) { if(EG(exception)) { zend_exception_error(EG(exception), E_ERROR TSRMLS_CC); } it seems current_execute_data is not setup when autostart is on, opposed to when you use session_start() function in your php code. I have been digging a lot without any luck, is there any of you that have a explanation of why current_execute_data is not setup yet? Br. /Kaspar
