Original Redmine Issue: 1587 from

Original Assignee: Wilson Snyder (@wsnyder)

Running the attached testcase with:

verilator_bin --lint-only --coverage

On version:

Verilator 4.020 devel rev v4.020-56-gbcb766b

Produces a segmentation fault and no other output.

It seems like this may have a similar root cause as #�. However, there are a few differences:

  1. This one is just comparing wires rather than memories
  2. This one requires "--coverage"
  3. There is no diagnostic given in this case
  4. This is a shorter testcase and uses fewer language features.
