New Comment:
This must be refcount limitation.
I see memory leak with 4.2.1-dev and 4.2.0-dev.
Scripting engine problem.
This problem may be suspended. It's not simple to fix.
May be we should let PHP die if refcount reached it's limit.
[yohgaki@dev HEAD]$ ./sapi/cli/php
<?php
$file = "-----";
for ($i = 0; $i<9000 ; $i++) {
$result_array["one"][$i] = $file;
$result_array["two"][$i] = $file;
$result_array["three"][$i] = $file;
$result_array["four"][$i] = $file;
$result_array["five"][$i] = $file;
$result_array["six"][$i] = $file;
$result_array["seven"][$i] = $file;
$result_array["eight"][$i] = $file;
}

try the follow code, it works on 4.0.6 but "Segmentation fault (core
dumped)" on CGI version and give no error message (and appear to keep
executing the code few more times on other httpd child process too) on
dynamic apache module version.
i've memory limited to 8M, and it's fine when for lopp as "$i<8000".
<?php
$file = "-----";
for ($i = 0; $i<9000 ; $i++) {
$result_array["one"][$i] = $file;
$result_array["two"][$i] = $file;
$result_array["three"][$i] = $file;
$result_array["four"][$i] = $file;
$result_array["five"][$i] = $file;
$result_array["six"][$i] = $file;
$result_array["seven"][$i] = $file;
$result_array["eight"][$i] = $file;
}
echo "done<BR>";
?>
