I'm running into a fault now when trying to run `go test -race`/
I get the same when I disable CGO (because it lists a CGO signal in the
fault):
`CGO_ENABLED=0 go test -c -race`
I've attempted to build a binary out of it and run it, with the same
results. This is not happening on all tests I attempt, just some tests.
I don' know of any C code I'm using, but I am importing various OTEL
packages, which might have CGO somewhere.
I'm not sure where to start debugging this, the internet has pointed to
other issues similar to this, not exact and none with circumstances that
are the same.
Here is the fault:
