* libguile/instructions.c: In loops, replace scm_op_last with SCM_VM_NUM_INSTRUCTIONS. (fetch_instruction_table): Protect the instruction symbols from collection. Before they were only marked by the name->opcode hash table, leading to races in which they could be collected. (scm_lookup_instruction_by_name): Protect the hash table earlier, as it's not actually a stack variable, since it's static.
