Oh and here's the backtraces for the production enviroment using PHP 5.3.3, APC
3.1.13 on CentOS 6 (x86_64). Backtrace have two options but still problem seems
to be the same:

This problem is wider than the report says! It's not just Centos 5 and 32bit.
Tested with 5.3.19, 5.4.9 and trunk 201212191230 and got bus error.
Suggested workaround by disabling mmap seems to work, so problem lies
in mmap handling. Real fix/patch would be nice and really appreciated.
5.3.19:
Core was generated by `sapi/cli/php test3.php'.
Program terminated with signal 7, Bus error.
