If DMD is running out of memory at compile time, I doubt it has to do with  
weird compiler bugs. DMD running out of memory is usually a sign of heavy  
compile time string manipulation, CTFE or template usage. Remember, DMD  
keeps all template instantiations in memory and every time a string or  
array is touched, a new copy is created (bug 1382).
