PHP segmentation fault when using more than 128M

http://serverfault.com – I have an install of SugarCRM. It is heavy on memory, which is a separate issue to deal with. In the meantime, any page that attempts to use more than 128M of memory, results in the Apache (mod_php) process halting with a segmentation fault: [notice] child pid 6852 exit signal Segmentation fault (11) If I set the PHP memory limit to 128M, then I never get the signal 11; I just get the normal PHP error telling me it cannot allocate any more memory.
