; This testcase ensures that CFLSteensAA doesn't try to access out of bounds indices
; when given functions with large amounts of arguments (specifically, more
; arguments than the StratifiedAttrs bitset can handle)
;
; Because the result on failure is effectively crashing the compiler, output
; checking is minimal.
