The same issue was submitted recently and it seems there is a problem.
To Reporter: Do not change parameter passed, but assgin to new var and
return new var to prevent segfault for now. Please update PHP Version
if you have tried with newer PHP.
Assigned to myslef so that I don't forget this.

No feedback. Closing.

I guess you have ob_end_clean() or ob_end_flush() in your auto prepend
file. Do you?
Anyway, does this happen with 4.1.0?

One more comment which I forgot before:
This does NOT happen when I do not use auto_prepend_file and call my
function inside the main script instead.

When using ob_start() with a script included via auto_prepend_file and
then doing something like this:
ob_start("my_flush");
function my_flush($buffer)
{
$buffer = preg_replace("/(<!--REPLACE\\s.*?-->)/e",
"parse(\"\\1\")",
$buffer);
return $buffer;
}
PHP 4.0.6 SIGSEGV's with this message in the error_log:
[Wed Jul 18 11:55:08 2001] Script: '/home/htdocs/test.php'
---------------------------------------
output.c(235) : Block 0x0824C940 status:

If I replace the line
$buffer = preg_replace("/(<!--REPLACE\\s.*?-->)/e",
"parse(\"\\1\")",
$buffer);
with
$newbuffer = preg_replace("/(<!--REPLACE\\s.*?-->)/e",
"parse(\"\\1\")",
$buffer);
it works fine.
Any ideas for a fix?
