Method and device for determining code exception

The invention provides a method and a device for determining code exception. The method and the device are used for providing a mode for detecting a concurrency problem of exception processing codes. In the method, a first thread of a first part of codes in exception handling codes and a second thread having a shared variable with the first thread can be executed concurrently, the second thread executes a second part of codes in normal function codes, and the first part of codes in the exception handling codes are executed according to the operation conditions of the first thread and the second thread on the shared variable. It is determined whether the first thread inappropriately operates the shared variable, thereby determining whether there is an exception in the exception handling code. In this way, a mode for detecting the concurrency problem of the exceptional processing codes is provided.
