Problem diagnosis technique of memory corruption based on regular expression generated during application compiling

A computer system for memory corruption diagnosis, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage media, and program instructions stored on at least one of the one or more tangible storage media for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• generating a pattern expression (PE) header file, wherein a plurality of common datatypes associated with a software program are pre-defined;
• modifying the software program to include the PE header file;
• modifying the software program to add an annotation symbol of a plurality of annotation symbols to a common datatype of the plurality of common datatypes;
• generating a PE for each of the plurality of common datatypes based on the modified software program;
• generating a PE table by merging the generated PE for each of the plurality of common datatypes;
• on determining that a memory corruption has occurred, transmitting a recorded state of the software program in a working memory storage as a core dump file to a server;
• identifying, by a dump utility, overlay content of the core dump file;
• converting, by the dump utility, the identified overlay content to a human-readable value, and;
• identifying a possible source program of the memory corruption by matching each PE stored in the generated table for each of the plurality of common datatypes against illegally written data in the converted overlay content.
