you need to disable httfix feature of Firefly as well as any additional SMT threads:

 $smp httfix=.f. httnp=1 $end

You can find additional information on this here.

With Firefly v. 8.0.0, one can use -nohttfix command line option. It is equivalent to

 $smp httfix=.f. $end

Kind regards,
Alex Granovsky
