Please see bug 116184 for a related case where neither Clang's assembler nor (at least current) GAS is an impediment to fixing the GCC bug. Both assemblers fully support two sections in different COMDAT groups that have the same section name. (Obviously, as this is the normal case for .rodata et al from C++ template instantiations.) GCC has the bug that it doesn't emit the correct `.section` directives when the section attribute is used, as fully demonstrated in bug 116184. This can be fixed in GCC and no assembler constraints prevent that working fine.
