I have what appears to be a deadlock(?) bug in my Julia package that is exposed only on Appveyor, and only when I test through the CI – if I enter the Appveyor VM through RDP and manually run tests, they pass…weird. Also, FWIW, this only happens on Julia 1.3. It all works for Julia 1.2. Please see this github issue for context.
Essentially, because the bug is only exposed through the CI, I need a way to generate a minidump or other debugging info via commands in the appveyor.yml, or I can RDP into the VM while my program is hanging and run commands manually from another terminal session (that might be the best option?).
I’m pretty new to debugging at this level, so any help (especially suggesting specific commands to run to generate the info I need) would be very much appreciated.
