Description:
------------
Everytime we start a script that is using more than approx. 300 MB memory, we get a segmentation fault in Apache2 (httpd-2.0.59) error_log.
This is the top of the GDB backtrace:

#0  0xb7deb0b7 in mallopt () from /lib/tls/libc.so.6
#1  0xb7deaf6e in mallopt () from /lib/tls/libc.so.6
#2  0xb7de9dcb in free () from /lib/tls/libc.so.6
#3  0xb7ccbcd2 in _efree (ptr=0x8521dec) at 

Reproduce code:
---------------
It's not related to a spefic code block/function call .
