Install phpMyAdmin (latest) with Apache 2.1.9 w/PHP 5.1.4.  APC using mmap(/dev/zero) and not SHM on brand new FreeBSD amd64 6.1 (GENERIC kernel).

The only modules I have running are: bcmath, ctype, curl, gd, mbstring, mysql, pcre, posix, session, simplexml, soap, sockets, sqlite, sysvmsg, sysvsem, sysvsem, sysvshm, tokenizer, xml, APC.  If I turn off APC in php.ini and run phpMyAdmin, I have zero issues.  Turn APC back on and everything works (including generating PDFs), but clicking on the Insert or Search tab causes httpd daemon to crash with segfault.

I  have tried clearing the cache and used different settings.  I have tried turning mmap off - make sure shmmax and other variables are set.  I set these to 64mb typically.  I have used APC before without issue, but now this is odd.

The server's memory is certified to work with dual-channel systems (which this is running on) and we've done several memory tests over the last few days to ensure we weren't working with bad RAM. 1GB of RAM is what this server has - two 512MB DDR pieces that are matched.  I'm pretty sure there's something in the APC code that doesn't like something one of those pages is doing.

Sorry, but your problem does not imply a bug in PECL itself.  For a
list of more appropriate places to ask for help using PECL, please
visit as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PECL.

Report PHPMyAdmins problems to the PHPMyAdmin team, and if you have a small script to reproduce this segfault, report a bug in

But this is not a pecl website problem
