Seems the bug disappears when the line
php_admin_value sendmail_path "/usr/sbin/sendmail -t -i
-finfo@example.com"
is removed from the Apache virtual host configuration.

Description:
------------
Segfault is happening sometimes on our test environment, Production
environment
has segmentation faults more frequent (has more requests apparently).
Have set Apache core dump configation and compiled PHP with debug mode
on the
test.
Receiving such error:
----------------------------
Program terminated with signal 11, Segmentation fault.
