The invention discloses automatic analysis method and device of the crash information of computer software. The method comprises the following steps of: (A) analyzing a dump file and outputting an analysis result; (B) parsing the output analysis result to acquire crash information; and (C) sorting the parsed dump file and storing a sorted result. The invention also discloses the automatic analysis device of the crash information of the computer software. In the invention, the crash dump file is analyzed by automatically calling a debugger provided by a toolkit of Debugging Tools for Windows to acquire the comprehensive and accurate crash information; and the crash information is sorted by using a crash address and a crash stack, therefore, not only the sorting accuracy is improved, but also the redundant information stored in a table is greatly reduced. By applying the invention, calculation staff in the field can accurately acquire the crush reason and provides reference for solving the software failures and optimizing the software.
