Descriptions and examples of defects
A Polyspace® Bug Finder™ defect is an analysis result that identifies a specific coding error or vulnerability. Use these categories of defects to understand your results.
Categories
- Numerical Defects
 Defects for numerical coding errors, division by zero, type conversion, and negative shift operations, math standard library
 
- Static Memory Defects
 Defects for static memory coding errors, out of bounds arrays, null pointers, standard memory and string library
 
- Dynamic Memory Defects
 Defects for dynamic memory coding errors, freed pointers, memory leaks, unprotected memory
 
- Data Flow Defects
 Defects for data flow coding errors, unreachable code, non-initialization, missing return statements, useless writes
 
- Resource Management Defects
 Defects related to resource handling such as unclosed file stream or use of a closed file stream
 
- Programming Defects
 Defects for programming coding errors, assignment versus equality operators, type mismatch, wraparound, string arrays
 
- Object Oriented Defects
 Defects related to C++ object-oriented programming such as class design issues or issues in the inheritance hierarchy
 
- C++ Exception Defects
 Defects related to C++ exceptions and their handling such as unhandled exception in anoexceptfunction or unexpected exception raised by athrowstatement
 
- Concurrency Defects
 Defects related to multitasking code
 
- Security Defects
 Defects related to security weaknesses and vulnerabilities
 
- Cryptography Defects
 Defects related to incorrect use of OpenSSL cryptography routines
 
- Tainted Data Defects
