> @wasphin 你试试看把`class D1 : public B1, public B2`改成`class D1 : public B2, public B1`还会挂么，看上去是c++多重继承导致的内存排列问题，`static_cast<B2*>(arg)`和D1继承B2的方式是冲突的。 有试过, 还是会挂, ~印象中挂的地方不一样了, 是一个 assert pid 的部分~. 重新试了一下, 调整继承顺序后报错一样. ``` 0x00000000004b2886 in xxx (this=0x0, path=<error reading variable: Cannot access memory at address 0x8>) xxx ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
