ERROR: Assert `size >= 1' failed in /root/synlig/synlig/frontends/systemverilog/uhdm_ast.cc:751.

I am using the following commands to load the files:

Yosys 0.33 version
plugin -i systemverilog
read_systemverilog -defer file_name1.sv
.read_systemverilog -defer file_name2.sv
read_systemverilog -defer file_name3.sv
read_systemverilog -defer top.sv

read_systemverilog -link
when I am linking with above command, I am getting the ERROR: Assert `size >= 1' failed in /root/synlig/synlig/frontends/systemverilog/uhdm_ast.cc:751.

hi
Thank you alaindargelas, I am trying to reevaluate the parameters from top file but the following error is coming

[alaindargelas]

Use read_systemverilog -P<name>=<value> .... rest of the command line

All the warnings above the error are of great concern. Please verify your design setup (Parameters).

The warning we are seeing is coming from one submodule where we just initialize the parameter later in top module we are assigning everything proper.
In previous project I followed the same but did not see any such issues
