bool Visit(BaseUnit unit, void pc) override { ...................................... delete unit;<=== 这里在一些特殊处理指令的情况下 return false; }; ----> if (!visitor.Visit(unit, pc)) { break; }

    pc = reinterpret_cast<InstA64 *>((Addr)pc + unit->Size());<===这里调用

========try to fix ================ reinterpret_cast<BaseInst>(unit)->Disassemble(); unit->Ref(); if (!visitor.Visit(unit, pc)) { break; } pc = reinterpret_cast<void>((Addr)pc + unit->Size()); unit->Release(); if(unit->RefCount() == 0) delete unit;

看看这样能不能解决问题, 祝好运!
