In this C# example, all exceptions are caught regardless of type, and a new generic exception is thrown, keeping only the message of the original exception. The original stacktrace is lost, along with the type of the original exception, any exception for which the original exception was a wrapper, and any other information captured in the ...
In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap .
Exceptions are defined by different layers of a computer system, and the typical layers are CPU-defined interrupts, operating system (OS)-defined signals, programming language-defined exceptions. Each layer requires different ways of exception handling although they may be interrelated, e.g. a CPU interrupt could be turned into an OS signal.

The location (in memory) of the code for handling an exception need not be located within (or even near) the region of memory where the rest of the function's code is stored. So if an exception is thrown then a performance hit – roughly comparable to a function call [24] – may occur if the necessary exception handling code needs to be ...

Using these exceptions to handle specific errors that arise to continue the program is called coding by exception. This anti-pattern can quickly degrade software in performance and maintainability. Executing code even after the exception is raised resembles the goto method in many software languages, which is also considered poor practice.
Processor exceptions generated by the CPU have fixed mapping to the first up to 32 interrupt vectors. [1] While 32 vectors (0x00-0x1f) are officially reserved (and many of them are used in newer processors), the original 8086 used only the first five (0-4) interrupt vectors and the IBM PC IDT layout did not respect the reserved range.
