Go crashing when run from Jenkins

[Grant Singleton]

I'm running go 1.14.2 on a windows 2019 server that is acting as a jenkins slave. The jenkins and the slave are connected with ssh and the master starts a python process on the slave and that invoked go. ```go version``` and ```go build``` crash. But if I ssh or rdp into the server and run either the python or go commands directly they work. Below are the crash dumps that I'm getting. Any ideas on what the stack dumps mean, and whats going wrong would be most appreciated.

```go version``` crash dump:

```

```

Go is windows 1.14.2, python is 2.7.17, Jenkins master is 2.204.5 running on Centos

I downgraded to go 1.13.10 and the crashes stop.
