#40735 [NoF->Opn]: stream_select returns 0 for php > 5.1.6

ID: 40735 User updated by: rodricg at sellingsource dot com Reported By: rodricg at sellingsource dot com -Status: No Feedback +Status: Open Bug Type: Streams related Operating System: x86_64 GNU/Linux -PHP Version: 5CVS-2007-03-05 (snap) +PHP Version: 5.2.3 New Comment: Just verified that I still see the same behavior with: php-5.2.3 openssl-0.9.8e gcc-4.1.2 I am using the same test script as before. Changing it to use: -O1 --with-openssl *or* -O2 --without-openssl gives the correct behavior. Previous Comments: ------------------------------------------------------------------------ [2007-08-03 21:12:20] blade at debian dot org It is even worse on the current Debian Sid, with 5.2.3-1+b1. It returns 0 and the modified arrays contain just nothing, but there is obviosly data available there. Tested with slightly adapted code from http://netevil.org/blog/2005/may/guru-multiplexing . ------------------------------------------------------------------------ [2007-03-24 01:00:01] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

I think I'll need an acccount on your machine to reproduce it. ------------------------------------------------------------------------ [2007-03-13 16:26:40] rodricg at sellingsource dot com The following script reproduces the behavior (for me): http://11434.com/stream_select.sh Changing -O2 to -O1 or removing --with-openssl fixes the problem. gcc version 4.1.2 openssl version 0.9.8d ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
