Original Redmine Issue: 1530 from

Original Assignee: Wilson Snyder (@wsnyder)

Running the attached test case with "verilator_bin --cc 2.v" produces:

%Error: 2.v:1: syntax error, unexpected IDENTIFIER
%Error: 2.v:1: Too many digits for 32 bit number: 11111111111
         ... As that number was unsized ('d...) it is limited to 32 bits (IEEE 2017 5.7.1)
         ... Suggest adding a size to it.

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