17:39 <tpw_rules> i am trying to build the liteiclink versa serdes example with yosys and getting "libc++abi: terminating with uncaught exception of type std::out_of_range: vector" during IO packing

17:41 <tpw_rules> i am using nextpnr-0.5 and yosys 0.27 built myself

17:53 <tpw_rules> it works fine on yosys 0.15 and nextpnr from 2022-01-03

18:06 <tpw_rules> so i guess something needs to be bisected
