What happened?
Passing a dict with an invalid key as the shared parameter to _interpreters.exec segfaults the interpreter (or aborts in a debug build):
import _interpreters _interpreters.exec(0, "1", {"\uFD7C\u5124\u7B91\u92E9\u1850\u39AA\u0DF2\uD82A\u2D68\uACAD\u92DE\u47C5\uFFD0\uDE0B\uAA9C\u2C17\\u6577\u4C92\uD37C": 0})Backtrace:
