SCHISM-WWM segmentation fault on wwm hotstart-write

[MariaVenolia]

Dear SCHISM users,

I am using two-way SCHISM-WWM model and trying to activate the "write hotfile", however I am getting the following "segmentation" error.
My wwminput.nml looks like so :

&HOTFILE
 LHOTF          = T                  ! Write hotfile
 FILEHOT_OUT    = 'wwm_hot_out'      !'.nc' suffix will be added
 BEGTC          = '20170916.120000'  !Starting time of hotfile writing. With ihot!=0 in SCHISM,
                                     !this will be whatever the new hotstarted time is (even with ihot=2)
 DELTC          =  2400            ! time between hotfile writes
 UNITC          = 'SEC'              ! unit used above
 ENDTC          = '20170917.120000'  ! Ending time of hotfile writing (adjust with BEGTC)

the Fortran error backtrace looks like :

I have had this problem across different machines and compilers.

I would like to resolve this so as to be able to write a wwm hotstart file at the end of my run.
Can you please advise ?
