Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

I cannot reproduce it.

In fact, after some check into windows system alert, I don't see any php crash process.
when calling a php page with this kind of code, apache logs return a 200 code (so it should be Ok), but in fact the html page is totally blank.
more stange,
I tried to do:
<?
echo "test";
exit();
<?=//$anything?>
?>
it also return a blank page !!
after deleting the line with <?=//$anything?>, it works normally....
I lost 3 days trying to understand what's going on until I find this....
(I'm not new in PHP !!!)





For your info, the same script work perfectly under windows 2003 32, apache 2.0, php4.4.9

It is a simple syntax error.  You must be suppressing error output/logging somehow 
or you would have seen the syntax error right away.  Since you have a syntax 
error, the script could not be parsed and thus could not be executed and you 
therefore get no output from it other than the error message.

This is a well known fact that // comments do not work on the same line than the opening php tag.

See the source of the page and you will certainly see the error message (between html tags).
