The embodiment of the invention discloses a method and equipment for detecting errors of a program, and belongs to the technical field of computers. The equipment for detecting the errors of the program can analyze the program to be analyzed, program analysis information is acquired, error attribute scale values of all constant value points in the program to be analyzed are acquired according to the program analysis information, and error prompts are given to invocation points corresponding to the constant value points with dangerous attributes of the error attribute scale values in the program to be analyzed. The method and equipment are mainly characterized in that detection of the errors of the program is converted into calculation of the error attribute scale values, thus, the error detection process is simplified, and the error detection efficiency of the program can be improved; when the program analysis information is acquired, the equipment for detecting the errors of the program can consider multiple kinds of sensitivity of the program to be analyzed, the complete information of each program point is acquired, the acquired error attribute scale values are accurate, and the error detection accuracy of the program to be analyzed is improved.
