We crash around or below codegen/compile.c:2663
A few levels up from the crash, we have this:
call PRTdoPrintNode(arg_node)
-----------------------------------------------
_unshare_( false, SACp_pinl_3510_iv)
--------------------------------------------
The clean approach, I suspect, would be to flatten "false". 
FLATGflattenExpression can do this for you.
