Memset is just doing what it is asked for. If a segfault occurs, it's not memset but some bug in your code or a library you use which is more likely to blame.

As you are using dbx, did you try its run time checking functionalities to figure out what is causing that issue ?

See that blog for details on how to enable it: Runtime Memory Checking : Leonard Li's Weblog
