4 years ago if (out.data_len != 0) { Buffer data(out.data_len); read_len = fread(data.GetBegin(), 1, data.Length(), fp); }
Buffer::Buffer(size_t length) : m_Ptr(nullptr), m_Size(length), m_IsNoCopy(BufferCopy) { if (m_Size > 0) { m_Ptr = malloc(m_Size); } }
看代码，应该是 out.data_len<0时，空指针了。

4 years ago 麻烦升级最新版本1.4.2， 另外请确认 Application中不存在多进程多次初始化问题，多进程多次使用相同参数初始化，是会出现问题。
