Apologies for the delay, I was away for the week. The solution is to simply not bother updating the backend when the assembler pointer is null, since getAssemblerPtr returning nullptr implies that we are emitting textual assembly, not an object stream, so we don't need to worry about relaxation or relocation anyway.
