co_instrumentation and co_monitoring Unexpectedly Set #133524
Description
Bug report
Bug description:
I ran into the following problematic case with gh-133221 (which had to be reverted):
import sys
import _testinternalcapi
def foo():
pass
def trace_temporarily():
sys._getframe().f_trace_opcodes = True
sys.settrace(print)
sys.settrace(None)
sys._getframe().f_trace_opcodes = False
trace_temporarily()
_testinternalcapi.verify_stateless_code(foo.__code__)
foo()
_testinternalcapi.verify_stateless_code(foo.__code__) # fails(See #133221 (comment).)
I would expect co_instrumentation and co_monitoring to have remained NULL.
