Where is argsV defined here? If you give a compiling sample might be able to debug with you.

This is basically taken from the Kladeiscope tutorials except using a tree walk instead of linearly.
_values
is a Stack of LLVMValueRefs.
FunctionCallExpression
is the type in my AST that represents a function call.
private void GenerateFunctionCall(FunctionCallExpression funcCallExpr)
{
var func = LLVM.GetNamedFunction(_module, funcCallExpr.FunctionName);
var argumentCount = (uint)funcCallExpr.Parameters.Count;
var argsV = new LLVMValueRef[Math.Max(argumentCount, 1)];
for (int i = 0; i < argumentCount; ++i)
{
Visit(funcCallExpr.Parameters[i]);
argsV[i] = _values.Pop();
}
var returnType = LLVM.GetReturnType(LLVM.GetElementType(LLVM.TypeOf(func)));
LLVM.BuildCall(_builder, func, out argsV[0], argumentCount, (returnType.Equals(LLVM.VoidType()) ? Marshal.PtrToStringAuto(IntPtr.Zero) : "fcall"));
}
Sorry for not providing enough info the first time around. Thanks for replying :)

So I just changed this line:
LLVM.BuildCall(_builder, func, out argsV[0], argumentCount, (returnType.Equals(LLVM.VoidType()) ? Marshal.PtrToStringAuto(IntPtr.Zero) : "fcall"));
to
LLVM.BuildCall(_builder, func, out argsV[0], argumentCount, "");
and it works
