test failed

[rgb000000]

Hi authors，
I test failed when I try "testOnly ofdm.SyncSpec".
My verilator version is "Verilator 4.008 2018-12-01 rev UNKNOWN_REV".
How can I solve this problem? Thanks in advance!
Is it because of dependency?

emmm... Besides, 'IterativeCORDIC.circularRotation' and 'IterativeCORDIC.circularVectoring' also failed.
