With my patch there are almost no problems. The problem is that
shutdown function won't execute - EG(timeout) flag should be cleared
before execution of shutdown function.
I can correct it if you want.

I took few days off. You know - holidays.
My config.nice :
'./configure' \
'--disable-all' \
'--with-apxs2=/usr/local/apache2/bin/apxs' \
'--with-config-file-path=/usr/local/apache2/conf/' \
'--enable-debug' \
"$@"
my script:
<?
function shutdown() {
echo strlen($GLOBALS['a']);
}
set_time_limit(1);
register_shutdown_function('shutdown');
while (true) $a.='a';
I use apache 2.0.47 with config.nice:
"./configure" \
"--enable-so" \
"--with-mpm=worker" \
"$@"
Now I have SIGSEGVs instead of hangs :) - probably longjump hit in the
middle of emalloc/erealloc and memory cache is corrupted.
I used my own module before, witch uses shared variables and locks -
thats why it hanged. Now - without my module it just crashes :).

Still waiting for the configure line..
------------------------------------------------------------------------
[2003-07-16 01:08:36] [EMAIL PROTECTED]
Could you also tell us what configure line you have used?
(so we can try to reproduce this too before applying any patches..)
