| | | | | | | | | | gh-110052: Fix faulthandler for freed tstate (#110069) faulthandler now detected freed interp and freed tstate, and no longer dereference them. Backport to 3.11: add pycore_pymem.h include to traceback.c. (cherry picked from commit 2e37a38bcbfbe1357436e030538290e7d00b668d)

| | | | | | | | | | | | | | | | | | | (#109272) gh-108987: Fix _thread.start_new_thread() race condition (#109135) Fix _thread.start_new_thread() race condition. If a thread is created during Python finalization, the newly spawned thread now exits immediately instead of trying to access freed memory and lead to a crash. thread_run() calls PyEval_AcquireThread() which checks if the thread must exit. The problem was that tstate was dereferenced earlier in _PyThreadState_Bind() which leads to a crash most of the time. Move _PyThreadState_CheckConsistency() from thread_run() to _PyThreadState_Bind(). (cherry picked from commit 517cd82ea7d01b344804413ef05610934a43a241)

| | | | | | | | | | | | | | (#109134) gh-104690: thread_run() checks for tstate dangling pointer (#109056) thread_run() of _threadmodule.c now calls _PyThreadState_CheckConsistency() to check if tstate is a dangling pointer when Python is built in debug mode.
