…honGH-148657) The option parsing in Modules/_zstd/decompressor.c had a missing Py_DECREF(value) before the early return -1 when PyLong_AsInt(key) fails. The identical code in Modules/_zstd/compressor.c line 158 has the fix. (cherry picked from commit 446edda) Co-authored-by: Michael Bommarito <michael.bommarito@gmail.com>
