Bug description:
On my mac M1 Sonoma (14.5), Python 3.13.0b4, I see this crash when registering an opcode monitor, calling the handler explicitly while it's enabled, and then restarting events. To reproduce:
import sys
def mymonitor(code, instruction_offset):
pass
tool_id = 4
sys.monitoring.use_tool_id(tool_id, "mytool")
sys.monitoring.register_callback(
tool_id,
sys.monitoring.events.INSTRUCTION,
mymonitor,
)
sys.monitoring.set_events(tool_id, sys.monitoring.events.INSTRUCTION)
mymonitor(None, 0) # call the *same* handler while it is registered
sys.monitoring.restart_events()Triggers an assertion failure (my minimal debugging suggests it's about some inconsistency with the "instrumentation_version"):
$ 3.13.0b4-debug/bin/python -X dev repro.py
Assertion failed: (debug_check_sanity(tstate->interp, code)), function _Py_call_instrumentation_instruction, file instrumentation.c, line 1347.
Fatal Python error: Aborted
