Blank page - child exit on bus error

timj

I'm having a big problem with a site that uses Php and Javascript.

It used to work just fine, but after the upgrade of Apache and Php 4, it does not work any more. It does not give me any errors neither.
The only thing I see is the message "unexpected child exit - bus error" (or something like that) in the Apache logs.

I've already tried the Error handler from Webkreator, but that only reports to me some minor errors. The major error that causes the blank page is never mentioned.

Can anyone please help me?

Many thanks in advance.

Can you help me track down the error?
I've been debugging for a long time now, without much results.

For instance, in some cases, the substr( ) function seems to fail (if I delete the line with substr( ), the code does not give a blank page any more). But on other lines, the substr( ) works just fine. And I am 100% sure that the code is correct, since it worked before and hasn't been changed.

So, what I'd really like is:
-that you help me find a way to avoid the blank pages (and instead output the error for instance), but I've already tried to do this via the tool from Webkreator;
AND/OR:
-that you help me fix this error (if you happen to know how).

Attached: the php script that fails (I've added a dummy .txt at the end, so that the site allows the attachment).

the blank page instead of the error is an ini setting in php.

No, it's not an .ini setting.
"Display_Errors on " only shows you the errors that PHP can catch. However there are also other, fatal errors that are not caught (according to Webkreator).

The tool from Webkreator has already helped me to catch the most simple errors (and mail them to me instead of putting them on the website where the users can see them).

Can somebody PLEASE help me with this?

I'm at a total loss here. I need some clue to find the error.

ANY input is welcome.
