http://blog.ksplice.com/2010/03/null-pointers-part-i/ So what if NULL doesn't crash the app ^^ ? https://www.securecoding.cert.org/confluence/display/seccode/EXP34-C.+Do+not+dereference+null+pointers I can't see MAP_FIXED anywhere in APR or apache code though. I am just suggesting it would be wise to prevent this from occurring. Not every platform / linux has /proc/sys/vm/mmap_min_addr . Sure it is not likely to be null, but it could be :) -- It is a wise father that knows his own child. -- William Shakespeare, "The Merchant of Venice"
