To reproduce bug do this test:
1) Turn off cookies at browser.
2) run file:
<?
session_name ("SESSID");
session_set_cookie_params (3600); 
session_register("test"); //registring tracks variable. 
if (!isset($test)) $test=1;
$test=$test++;
echo '<a href="'.$PHP_SELF.'?SESSID='.session_id().'">test</a>';
echo '<br><a href="'.$PHP_SELF.'?SESSID=c:\123">test2</a>';
?>
3) Click on a "test2" link
4) Apache child will crash and php will write message like
Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

Testes on OS/2 (PHP 4.1.2) and win32 (PHP 4.1.1). PHP is installed as Apache module.

Thanks for reporting, but this has been reported already. IIRC.

I've looked bug reports, but there is no exactly the same segfualt report. I'll keep this report open.

Cause is known and there are sevral reports already for the same cause, but different segfaults.
