BTW: you can do
flx --debug --force filename
The --debug does debugging stuff, and --force makes it
recompile everything.

I get this:
SYSTEM FAILURE
[C func body, vars] Can't find index 4229
and with the debugging:
//Reparent 4229 <-- 3752
and:
// 3749 -> new_DLL_List (function) rec.flx: line 14 col 1 to line 18
col 1
// 3750 -> T (type variable)
// 3751 -> _rqs_new_DLL_List (insert) rec.flx: line 14 col 1 to line
18 col 1
// 3752 -> x rec.flx: line 16, cols 5 to 24
so it is talking about the x here:
fun new_DLL_List[T] (n:T):&DLL_List[T] =
{
var x : DLL_List[T];
return &x;
}
Well:

So it seems the inliner has eliminated almost everything --
after all your code doesn't do anything useful!
but it still shouldn't error out.
