Original Redmine Issue: 1552 from https://www.veripool.org

Original Assignee: Wilson Snyder (@wsnyder)

Running the attached testcase with:

verilator_bin --lint-only 4.sv

On version:

Verilator 4.020 devel rev v4.020-18-g4361fb8

Does not terminate in a reasonable amount of time. It reports that it is recursively including itself, but it is not obvious why it thinks it needs to do that.

Thanks. Basically the double ticks means concatenate and as there's no following token it comes from the auto-inserted `line, so it picking the filename while strange isn't really wrong per-se. Fixed it to properly stop on the recursive include.

Fixed in git towards eventual 4.022 release.
