An assertion is failing in the code in method  
FunctionDeclaration::toObjFile(int).  The assertion looks like it's  
expecting v->csym to be either null or non-null.

What this means, I have no idea.  Generally bugs like this you have to  
narrow down what's causing the bug in your D source, and then report the  
bug on bugzilla.
