Many reversing techniques for data structures rely on the knowledge of memory allocation routines. Typically, they interpose on the system's malloc and free functions, and track each chunk of memory thus allocated as a data structure. However, many performance-critical applications implement their own custom memory allocators. Examples include webservers, database management systems, and compilers like gcc and clang. As a result, current binary analysis techniques for tracking data structures… CONTINUE READING
