Bug #15486: 'Invalid range end' with eregi_replace() under certain conditions.

From: cahagn_o@epita.fr Operating system: Linux PHP version: 4.0.6 PHP Bug Type: *Regular Expressions Bug description: 'Invalid range end' with eregi_replace() under certain conditions. There's an annoying bug with eregi_replace() which sometimes send Invalid Range End. This is reproducible with Linux RH7.2 and PHP 4.0.6 compiled '--with-regex=system'. I couldn't find this bug on bugs.php.net. This might be a known bug but, please, don't close it, I would really like to know on which systems the problem occurs exacly so as to add workaround on a Webmail client FAQ I wrote: http://nocc.sf.net/ It happens on this system (which I'm not the Webmaster of): http://www.okkaskole.no/~brr/test.php I couldn't reproduce the problem on Win2k+Apache 2.0.28+PHP 4.0.6 as CGI. Some other reports: http://www.webgenerator-x.com/support_forum.php3?op=viewtopictree&topic_id=55 http://www.squirrelmail.org/wiki/RedHatOutdatedGlibc I will attach testcase, which is long but the user on the above system couldn't reduce testcase. And I cannot reduce it myself as I don't have the bug on my system. The regexp might seem to be complicated but it runs very fine on many Web servers (NetBSD w/ Apache, Windows w/ Xitami, etc.) but some servers under certain conditions which makes it hard to reproduce. Fortunately, this time, it seems that I have a 100% reproducible testcase. -- Edit bug report at http://bugs.php.net/?id=15486&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=15486&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=15486&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=15486&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=15486&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=15486&r=support Expected behavior: http://bugs.php.net/fix.php?id=15486&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=15486&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=15486&r=submittedtwice
