gh-67413: Fix segfaults and multiple leaks in the lzma and bz2 modules by ZackerySpytz · Pull Request #7822 · python/cpython

@ZackerySpytz 

lzma.LZMADecompressor and bz2.BZ2Decompressor objects caused
segfaults when their __init__() methods were not called.

lzma.LZMADecompressor, lzma.LZMACompressor, bz2.BZ2Compressor, and
bz2.BZ2Decompressor objects would leak locks and internal buffers when
their __init__() methods were called multiple times.
