terminate called after throwing an instance of 'std::out_of_range' during nextpnr_ice40::log_crit_paths #1379

nextpnr crashes with the following message: 

<previous output removed>
Info: Critical path report for cross-domain path 'posedge CLK$SB_IO_IN' -> 'posedge CLK$SB_IO_IN_$glb_clk':
Info:       type curr  total name

To reproduce, check out my repo and run command.sh: https://github.com/Barabas5532/crush/commit/59d3a06fb4c04f1fbbbd76f77e432f0439987abc

I can also explain how to generate the JSON file from the verilog source if required. This command uses a pre-generated JSON file.

The JSON file was produced by yosys version:

Yosys 0.43 (git sha1 ead4718e5, g++ 14.2.1 -march=x86-64 -mtune=generic -O2 -fno-plt -fexceptions -fstack-clash-protection -fcf-protection -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -ffile-prefix-map=/build/yosys/src=/usr/src/debug/yosys -fPIC -Os)

Will take a look at this tommorow morning since it's late here. It might be worth a try to try current master.
