Just-in-Time (JIT) debugger. When the application throws an unhandled exception, Dr. Mingw attaches itself to the application and collects information about the exception, using the available debugging information.
Dr. Mingw can read debugging information in DWARF and Stabs formats — generated by the Gnu C/C++ Compiler, and in a PDB file — generated by the Microsoft Visual C++ Compiler.
Windows XP or later is required. It relies upon the DbgHelp library to resolve symbols in modules compiled by the Microsoft tools.
