Hello,

i am confronted with odd behavior of php 5.2.10. I compiled and packaged the
same way like other prior versions.
If i install 5.2.10 and reload page (sefrengo cms) the page is outputed
completely twice.when scrolling down i see same page again incl. <doctype

<html> </html> etc. Downgrading to 5.2.9 solves problem and page looks like intended. somebody has already heard of problems like this? i do not really know in which direction to look, current buglist contains no fitting descriptions.. i guessed a relation to bug #48994 but was not confirmed, also current 5.2.11rc2 showed odd behavior.

Any ideas?

Thanks,
Andre

Is it reproducible with simple page? something like:
<?php
echo "Hello, world!\n";
?>

If it isn't, you'll need to find minimal script which shows the problem.

Also, you can ask your CMS's authors if they know about this problem

i tried some situations but in my case all works fine. on other machine same
cms with same page shows up correctly. (same rpms installed)
problem seems to be outputbuffering: index.php of sefrengo does in line 37
ob_start()
if i deactivate this line page works correctly.

next is line 433 in index.php of sefrengo, there is a eval();
if ob_start in line 37 is active but this line gets deactivated the page
also works ok.
the eval in this case evaluates an "echo $output". $output contains a
html-div, some text etc. which is modifying main-html
in 5.2.10 complete page is outputed twice, returning to 5.2.9 page is ok

Also, you can ask your CMS's authors if they know about this problem
i think problem is unknown but will ask there.
maybe we succeed to isolate problem.

Thanks,
Andre
