Description

Running the attached testcase with:

verilator_bin --lint-only 1.sv

produces:
%Error: out2/queue/id:000998,src:000000,op:havoc,rep:32:5: EOF in '/* ... */' block comment
fatal flex scanner internal error--end of buffer missed

This is on version: Verilator 4.020 devel rev v4.020-19-gc73336f

This is a similar (though not identical) result as was seen in this bug: https://www.veripool.org/issues/1532-Verilator-Fuzzer-fatal-flex-scanner-internal-error-end-of-buffer-missed
