gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the
CPython interpreter within GCC, allowing you to write new compiler
warnings in Python, generate code visualizations, etc.
It ships with "cpychecker", which implements static analysis passes for
GCC aimed at finding bugs in CPython extensions. In particular, it can
automatically detect reference-counting errors:
Highlights of this release:
* You can now create custom GCC attributes from Python, allowing you
to add custom high-level annotations to a C API, and to write Python
scripts that will verify these properties.
* The "cpychecker" code has too many improvements to list here, and
has now detected many reference-counting bugs in real-world CPython
extension code. Some success stories can be seen at:
The usability and signal:noise ratio is greatly improved over
previous releases. It can now emit HTML reports showing the path of
execution through a function that triggers a particular error.
