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:

zend_variables.c(117) : Actual location (location was relayed)
[Wed Jul 18 11:55:08 2001] [notice] child pid 30192 exit signal Segmentation fault (11)
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?
