There is a very important patch to GD for this very problem of  
crashing with antialiasing (it's not a MapServer problem).  Search  
the list archives for details.  It's not in the official GD release,  
and I don't know if any linux binary packages have it, so you'll  
probably have to build GD yourself.  I thought I saw it mentioned on  
the MapServer site somewhere, but a search didn't turn up anything.
