Dynamic software analysis with memory debugging and memory leak protection

IBM Rational® Purify® for Linux® and UNIX® is a dynamic software analysis tool for UNIX application development. This software provides memory debugging and leak protection. Rational Purify monitors and analyzes how a program uses memory and reports errors with source code details that determine the cause and location of the error.

Memory debugging identifies difficult to find memory errors, such as uninitialized memory access, buffer overflow, and improper freeing of memory.
Memory leak protection identifies memory blocks that cannot be referenced along with memory blocks that are never freed.
Binary instrumentation technology instruments code at the byte or object level, can be used with third-party libraries, and does not require access to source code.

Memory debugging

Rational Purify analyzes memory accesses and manipulations by your program and identifies memory errors before they occur.
This software provides detailed information, such as the error location (function call stack) and the size of the affected memory.
Rational Purify offers APIs that you can invoke from your program or debugger to further assist you in debugging memory problems.

Memory leak protection

Rational Purify scans all memory and reports all memory blocks without any pointers as memory leaks.
It reports all blocks as potential leaks when there are no pointers to the beginning of the block, but there are pointers to the middle of the block.
This software specifies the line where the leaked memory was allocated.
Rational Purify lets you debug at the memory allocation site where the leak is reported, and then tracks what you are doing with that pointer and where you are overwriting it.

Binary instrumentation technology

Rational Purify does not require recompilation to analyze code.
This software analyzes third-party libraries, even if you do not have the source code.
Rational Purify supports C and C++.
