Just tried to reproduce it on Centos 6.2 install (without APC), works
just fine for me. I suspect it's some APC issue, does it reproduce for
you without APC loaded?
Yes, as I mentioned in previous message and in the comments of that bug.
I'll hilight the relevant backtrace in this message.
Did you tried to run it couple of times? In my tests in one machine
it seemed sometimes run without any problems but then ctrl-c and running
again got the sigbus.

to get it to use version that i did compile.
# cat test3.php
<?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 {
$p2 = popen("sapi/cli/php test3.php 100", "r");
while (1) include 'test.tpl';
}
