With php5.3.4 (201011111730) + APC 3.1.4 upload progress return correct information (but sometime cause segfault on first call)

With php5.3.4 (201011111730) + APC 3.1.4 upload progress don't return any information and cast a lot of warning.

PHP Warning:  Unknown: Potential cache slam averted for key 'upload_d1d1d989cddc6b8281e5cb49df9029ba' in Unknown on line 0

With apc-3.1.6-dev (expecially commit 305258), no more PHP Warning. But apache segfault (and, no upload information provided)

I have the same problem with the PHP 5.3.3 dotdeb package, which uses the released 3.1.5 version of APC.

apc_fetch() now always returns false :(

(forgot to specify I was running Debian Lenny)

Any update on that segv?

I have fixed the problem as such (i.e the slam_defense was 
preventing upload_progress from slamming the cache).

But I didn't see a segv at all.

http://news.php.net/php.pecl.cvs/14973

Please check again and if you've got a segv, please re-open with a back-trace.

i have got a segv with php 5.3.4 and apc 3.1.6
