Previous Comments: ------------------------------------------------------------------------ [2010-05-12 11:47:40] mike@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2010-04-30 20:59:33] slusarz at curecanti dot org I don't have the time to try to track this down further. The bug still exists, but it obviously requires something more (in terms of program state) than a simple test script can recreate. ------------------------------------------------------------------------ [2010-04-30 00:09:35] felipe@php.net I cannot reproduce this. We need a proper test case. ------------------------------------------------------------------------ [2010-04-26 21:57:21] slusarz at curecanti dot org I can't provide a simple test case - it appears that it takes something more than just appending a write filter to a stream (the error is occurring after tens of thousands lines of code were run). But I did manage to determine that this only happens if the script exits soon after the filter_append with an explicit 'exit' call. e.g.: ----- [...code...] $fp = fopen('php://temp', 'w+'); stream_filter_register('user_filter', 'User_Filter_Class_Name'); stream_filter_append($fp, 'user_filter', STREAM_FILTER_WRITE); print "TEST"; exit; [...code...] ----- will segfault and will not output "TEST" to the browser. If 'exit;' is removed, no segfault occurs. ------------------------------------------------------------------------ [2010-04-25 12:08:08] pajoye@php.net Thank you for this bug report.
