Literally the first design I run through @XilinxInc Vivado 2016.4 segfaults in "opt_design -sweep -propconst -resynth_seq_area".pic.twitter.com/8cp3GEVpEd

At least with a segfault it should be easy to convince Xilinx support that it is a bug in Vivado. Getting them to create a CR can be hard..
If anyone wants to reproduce the bug, here is the example design that triggers it: http://svn.clifford.at/handicraft/2016/vivadosig11/ …

what if u dont give any switches to opt_design?

As the log I posted suggests, the problem is -resynth_seq_area, but just -resynth_area is sufficient to crash Vivado.
