Kind Regards Giacomo From: Jason Lowe-Power <ja...@lowepower.com> Date: Wednesday, 19 October 2022 at 16:02 To: The gem5 Users mailing list <gem5-users@gem5.org> Subject: [gem5-users] Re: PyGILState_Check() failure Can you describe what your python run script is doing? It looks like the error is happening when dumping stats. To do this, gem5 does python->C++->python, which may be causing the problem. Though, that's just a guess. Can you create a minimal example that causes the error so we can reproduce it?

"pybind11::object_api<>::operator() PyGILState_Check() failure." The same problem is reproduced in Ubuntu 20.04 and 22.04. My guess is some simobjects grabbed the lock without releasing it. But I am not sure. Can someone hint us on how to debug such exceptions? == GDB stack === #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50 #1 0x00007ffff6bc8859 in __GI_abort () at abort.c:79 #2 0x00007ffff6fa0911 in ??
