Original Assignee: Wilson Snyder (@wsnyder)


Running "verilator_bin --cc 5.v" produces:

%Error: 5.v:3: Unterminated string
%Error: 5.v:2: Unsupported or unknown PLI call: $lay
 initial $lay(*Hello!=nendmodule
          ^~~~
%Error: 5.v:2: EOF in (*
 initial $lay(*Hello!=nendmodule
              ^

This was run with:
Verilator 4.019 devel rev v4.018-33-gcb115e1a

And also fails with:
Verilator 3.916 2017-11-25 rev verilator_3_914-65-g0478dbd

Thanks for the testcase. Flex EOF detection wasn't properly handled.

Fixed in git. As this is unlikely to be hit by users, closing immediately rather than waiting for a release.
