Hi,
I started hitting Py_FatalError("Invalid thread state for this thread")
in pystate.c when a thread bootstraps since my upgrade to Python 2.4.2
(was using 2.4.1 previously).
I'm embedding Python in C++, using multiple interpreters and threads.
I think the problem is that PyThreadState_Delete (which is used when I
destroy thread states and interpreters) is not making the same clean up
that PyThreadState_DeleteCurrent is doing:
if (autoTLSkey && PyThread_get_key_value(autoTLSkey) == tstate)
PyThread_delete_key_value(autoTLSkey);
If a thread id is reused (and this often happens), and the previous
thread used PyThreadState_Delete instead of PyThreadState_DeleteCurrent,
an old and invalid value for autoTLSkey is stored, and that is
triggering the Py_FatalError.
Thanks.
