Hi Maintainer

Trilinos FTBFS with an ICE with gcc-8 8.2.0-15 (8.2.0-14 was fine).

Confirmed on reproducible builds [1].

In file included from 
/build/1st/trilinos-12.12.1/packages/kokkos/core/unit_test/serial/TestSerial_SharedAlloc.cpp:45:
/build/1st/trilinos-12.12.1/packages/kokkos/core/unit_test/TestSharedAlloc.hpp: 
In instantiation of 'void Test::test_shared_alloc() [with MemorySpace = 
Kokkos::HostSpace; ExecutionSpace = Kokkos::Serial]':

/build/1st/trilinos-12.12.1/packages/kokkos/core/unit_test/TestSharedAlloc.hpp:129:57: 
internal compiler error: in lookup_template_class_1, at cp/pt.c:9459
       RecordFull * rec = RecordFull::allocate( s, name, size * ( i + 1 
) );
                                                         ^~~~
Matthias suggested this looks like upstream #88995.
