Occamy Verilator simulation error

[pquanganh3105]

Hi Nils,

I have pulled new revision. However, I found this error when ran command make bin/occamy_top.vlt: 

verilator_bin: ../V3Ast.cpp:1144: void AstNode::v3errorEndFatal(std::ostringstream&) const: Assertion `0' failed.
%Error: Verilator aborted. Suggest trying --debug --gdbbt
%Error: Command Failed occamy/install-snitch/verilator-4.100/bin/verilator_bin --Mdir work-vlt/ -f work-vlt/files -Wno-BLKANDNBLK -Wno-LITENDIAN -Wno-CASEINCOMPLETE -Wno-CMPCONST -Wno-WIDTH -Wno-WIDTHCONCAT -Wno-UNSIGNED -Wno-UNOPTFLAT -Wno-fatal --unroll-count 1024 -Wno-SYMRSVDWORD -Wno-BLKLOOPINIT --trace --prof-cfuncs -j 4 --cc --build --top-module testharness

I have installed the correct version of Verilator 4.100 followed this link: https://pulp-platform.github.io/snitch/ug/setup-iis/

How can I fix that? 

Many thanks
