I wonder why I did not find that one when searching for related information. Sorry, and thank you all for your help!! Previous Comments: [2008-07-23 08:30:15] lmalgras at tennaxia dot com It seems to be the same issue as reported on #43487 [2008-07-20 11:16:19] [EMAIL PROTECTED] What gcc version that openSuSE has? Try this on the ubuntus: Using fresh, just untarred/gunzipped php sources: # ./configure --disable-all --disable-cgi --enable-debug # make # php -n -r '$float=1e-6; var_dump($float, strval($float));' [2008-07-17 16:02:15] rudolphi at chemie dot uni-kl dot de On openSUSE 11, the problem cannot be reproduced either. Though, changing everything to openSUSE is not an option for me, sorry (usability is a nightmare). Isn't there any Ubuntu user out there who can reproduce this? [2008-07-17 15:02:31] rudolphi at chemie dot uni-kl dot de The error can be reproduced on two different machines: - my development machine (Core Duo 2300, 1GB) and - the production machine (Core 2 Quad 9450, 2GB), both running the 32bit version of Ubuntu 8.04 (including all updates, but no "proposed","backports" stuff) I cannot reproduce the error on - another testing machine (Core 2 Duo 6550, 2GB) running Ubuntu 7.10 64bit - a Windows 2003 Server - a Win XP Professional running Xampp I will try with some *nix-live cds and post the results very soon. [2008-07-16 19:18:24] [EMAIL PROTECTED] Are you able to reproduce this on some other machine? Or some other *nix / linux distro? Or does it only happen with on one single machine and OS?
