Executing

verilator --trace -cc combined_main.v --exe sim_main.cpp

%Error: Verilator internal fault, sorry. Consider trying --debug --gdbbt
%Error: Command Failed /usr/local/bin/verilator_bin --trace -cc combined_main.v --exe sim_main.cpp

Running gplcver on the same code does not appear to complain.

A quick look shows the duplicate logic eliminator is blowing up the stack, something to do with all of the functions in your program. Needs more analysis.

The gate dedup logic was getting stuck, I added a recursion limit.

Fixed in git towards 3.881.
