The following module should output 4'b1111 but Verilator GIT 14fcfd8 outputs 4'b0001 instead.

module issue_005(y);
  wire [3:0] a;
  output [3:0] y;
  assign a = 4'b0010;
  assign y = $signed(|a);
endmodule

A self-contained test can be found here:

This was caused by the fix for #�, and did not exist in previous versions.

Please see notes in #�.

Fixed in git; never in release.
