python3-debug

Debug version of the Python runtime

python3-debug provides a version of the Python runtime with numerous debugging features enabled, aimed at advanced Python users such as developers of Python extension modules. This version uses more memory and will be slower than the regular Python build, but is useful for tracking down reference-counting issues and other bugs. The bytecode format is unchanged, so that .pyc files are compatible between this and the standard version of Python, but the debugging features mean that C/C++ extension modules are ABI-incompatible and must be built for each version separately. The debug build shares installation directories with the standard Python runtime, so that .py and .pyc files can be shared. Compiled extension modules use a special ABI flag ("d") in the filename, so extensions for both versions can co-exist in the same directory.
