--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Possibly some mishandling of EXCESS_PRECISION_EXPR in the frontend. We
build the compare starting with
(gdb) p debug_generic_expr (orig_op1)
<<< Unknown tree: excess_precision_expr
4.24199981689453125e+1 >>>
Note with -fexcess-precision=16 the testcase behaves as you like.
