APC takes a LOCK_EX in exactly one place, apc_bin_dumpfile(), which does not

Hi!
Oh? Did I understand you correctly? If you can code PHP that crashes
PHP, it's that codes fault not PHP's fault? I've always thought PHP
to be high level programming language where PHP handles things for
you and you can't code anything that crashes it like that with
bus error?

I understand your sentiment.
And I try to understand your technical point of view. I've thought
that PHP handles concurrent stuff so that those kind of things

to do stuff.
But I
I understood you correctly using temp file and then rename should fix
that? Like this?
file_put_contents('test.tpl.tmp', ?php #.str_repeat('A',
mt_rand(4000, 5000)). ?\n, LOCK_EX);
rename('test.tpl.tmp','test.tpl');
Exactly!
You could also do it like this:
$tmpname =
Hi,
If someone wants access to machine where you can reproduce this
send me email. It's not just one machine where I can reproduce
this, so can't blame hardware.
Reproduced this there in CentOS 6.3 default php, php-5.3.19, php-5.4.9
and php-trunk-201212200830.
What I noticed that with trunk I
Hi!
?php
if ($argv[1] 0) {
while ($argv[1]--) file_put_contents('test.tpl', ?php
#.str_repeat('A', mt_rand(4000, 5000)). ?\n, LOCK_EX);
} else {

while (1) include 'test.tpl';
}
?
Yes, I can now reproduce this on my machine too.

I'm not sure how any lock would help, since locks are optional, meaning
you still can do the same thing without the locks.

I did come up with a problem in my server crashing with SIGBUS.
After long testing/tracing found:

Unfortunately that bug report seems to have only some workaround to
disable mmap(). I
