Please try using this CVS snapshot:
http://snaps.php.net/php5-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5-win32-latest.zip
And provide a script that actually is usable. For that script it's
perfectly fine to give an error..
Also: The version string in the 'Version' field in the bug reports MUST
start with a number 4,5 or 6.

Can not reproduce, there's been couple of reports and none them with
proper way to get this reproduced. Most likely user error.

confirmed with CVS
again, exit() in sess_write() cause this issue
other modules after session module is not shutdown properly
i don't see any fix in the php4-src/ext/session/ source

i guess i've found the bug
it's a "exception safe" problem as c++
well, not php5 exception, i meant zend_bailout(longjmp)
when write handler issue a Fatal error, will trigger zend_bailout() and
skip ALL other modules rshutdown, including the one right after
session_flush_data();
session.c:
static void php_session_flush(TSRMLS_D)
{
if(PS(session_status)==php_session_active) {
php_session_save_current_state(TSRMLS_C); <-- NOT exception
safe using for mod_user.c
}
PS(session_status)=php_session_none; <- WON'T executed when
zend_bailout
}
suggested fix:
mod_user.c :: function PS_WRITE_FUNC(user)
chnage
======
retval = ps_call_handler(PSF(write), 2, args TSRMLS_CC);
======
to
======
zend_try {
retval = ps_call_handler(PSF(write), 2, args TSRMLS_CC);
} zend_end_try();
======
