Hi, since pyopencl switched to using pybind11 I am experiencing crashes "pybind11_object_dealloc(): Tried to deallocate unregistered instance!“, likely triggered in pybind11/detail/class.h: pybind11_object_dealloc() / clear_instance() As far I can tell this occurs only if the garbage collection routine tries to collect a pyopencl._cl.NannyEvent. Disabling garbage collection and the crashes disappear.
Because of these crashes being related to garbage collection they occur seemingly randomly, I have not been able to reproduce them with a simple program, only with my large multi-threaded experiment control program... I am using Anaconda Python 3.6 on Windows with pyopencl from git built (Visual Studio 2017) myself , with pybind11 2.2.3 installed via conda. Same crashes I also observed on a mac. I am looking for advice to debug this issue further, if needed I could provide more detailed stack traces. Should I also send the report to the pybind11 maintainers? thanks for any help Gregor _______________________________________________ PyOpenCL mailing list PyOpenCL@tiker.net https://lists.tiker.net/listinfo/pyopencl
