Addressed a bug in the gas assembler for i386 where certain complex expressions could lead to unbounded recursion, causing a stack overflow. The issue occurred when an expression involved both X_add_symbol and X_op_symbol. The fix ensures that the assembler correctly handles these cases by marking symbols as resolving during the recursive calls and clearing the mark afterwards, preventing infinite loops.
