Rosetta compilation error with gcc-10

Dear all,

I am trying to compile ROSETTA 3.12 on Red Hat Enterprise Linux Server release 6.5. I install the gcc (GCC) 10.1.0, and run the follow command

     ./scons.py bin mode=release -j 60

I get some error information like:

   scons: *** [build/src/release/linux/2.6/64/x86/gcc/10.1/default/protocols/vip/VIP_Mover.os] Error 1

In file included from src/protocols/analysis/PackStatMover.cc:17:

src/core/scoring/packstat/compute_sasa.hh: In function ‘core::scoring::packstat::PackstatReal core::scoring::packstat::compute_sasa_generic(utility::vector1<T>&, core::scoring::packstat::PackstatReal, bool)’:

src/core/scoring/packstat/compute_sasa.hh:410:41: internal compiler error: unexpected expression ‘(short unsigned int)l->atom_sasa_masks.ObjexxFCL::FArray2D<ObjexxFCL::ubyte>::operator[]()’ of kind implicit_conv_expr

  410 |    ctr += bit_count[atom_sasa_masks[ l ]];

Is it caused by the gcc comiler? If I use a gcc of lower version, would it work?

Thank you in advance!
