[New-bugs-announce] [issue40048] _PyEval_EvalFrameDefault() doesn't reset tstate->frame if _PyCode_InitOpcache() fails

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

tstate->frame is a borrowed references to the current frame object. It's set tp the frame at _PyEval_EvalFrameDefault() and resets to frame->f_back at _PyEval_EvalFrameDefault() exit.

Problem: when _PyCode_InitOpcache() fails, tstate->frame is not reset to frame->f_back.
