Thanks Nanmiao. That unfortunately does not help... There are two other simple things you can try before going all-in with debugging. The first is to run the test with "--hpx:debug-timing-log" (ironically this seems to hang, I'll try to fix that independently). You should see on the second line "creating distributed runtime" or "creating local runtime". Let me know which one. The second is to check if adding "auto rt = hpx::get_runtime()" at the top of hpx_main also hits an assert or if it works fine.
Beyond that you can try putting a break point on this line: https://github.com/STEllAR-GROUP/hpx/blob/291736b9538afed58269dd1611fd71b8ea839f1f/src/runtime_distributed.cpp#L1483. That should be executed before you enter hpx_main on the worker thread where hpx_main gets executed. Running with --hpx:threads=1 might make it a bit easier. Does the assert fire every time you run the test? ________________________________ From: hpx-users-boun...@stellar-group.org <hpx-users-boun...@stellar-group.org> on behalf of Nanmiao Wu <wnan...@lsu.edu> Sent: Wednesday, June 24, 2020 3:49:55 PM To: hpx-users@stellar-group.org Subject: Re: [hpx-users] Possible HPX errors Hi Mikael, Thanks for your help!

I have put the details in the gist https://gist.github.com/NanmiaoWu/c8aedaf74c28d025bb0778a72ab198fe<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgist.github.com%2FNanmiaoWu%2Fc8aedaf74c28d025bb0778a72ab198fe&data=02%7C01%7Cwnanmi1%40lsu.edu%7C1b35b55be44a43267b0808d8181dfe4c%7C2d4dad3f50ae47d983a09ae2b1f466f8%7C0%7C0%7C637285864398629298&sdata=CFJEbUsqX3t%2B1V5yjQdmiT05nhcFEhMi5CRTFcf9b0E%3D&reserved=0> Thanks!
