OpenTelemetry with PythonCall can yield LLVM ERROR: Cannot emit physreg copy instruction

[MartinWolke]

Hi!

Thank you for writing this package; it's awesome!

I've been experimenting with OpenTelemetry (OpenTelemetry v0.3.0) and stumbled over a weird interaction when combined with the PythonCall (PythonCall v0.9.13) Package. Running the following code reliably crashes Julia (I tried with Julia 1.9.0, Julia 1.9.1, and Julia 1.8.5; all installed with Juliaup) for me.

using PythonCall
using OpenTelemetry

with_span("test") do
    error()
end

The weird thing is that PythonCall isn't even used.

Julia crashes with

LLVM ERROR: Cannot emit physreg copy instruction

[28652] signal (6.-6): Aborted
[...]

Do you have any idea what might cause the issue? I couldn't find anything so far. I'll post a complete stack trace below.
