Pinpoint hard to find bugs

Rational PurifyPlus’s patented Object Code Insertion (OCI) technology gives Rational Purify the power to check for fatal or corrupting memory-access errors in unmanaged code. Not only in your source code, but also in libraries for which you do not have access to source code. Purify checks Microsoft components, including ActiveX controls, COM/DCOM components, ODBC components, DLLs, and third-party components, whether you have access to source code or not. No recompile is necessary to allow Purify to pinpoint hard to find bugs such as reading from uninitialized memory or accessing beyond the end of an array.
