you may also use the script(1) command which automatically stores stdout
and stderr into a text output file. But redirecting stderr is also fine.
I think we've gathered a lot of debugging info but we need to make one
last step to find the cause of the panic. Can you please run the
attached script and file the outcome to the PR?
It will give us the values of some variables and I'm pretty sure a net
maintainer will find what's causing your panic and can produce a fix for
it. As soon as we've got the additional debugging information, I'll
forward your PR to the appropriate maintainer(s).
Thank you for your effort - I know it's been a pain for you to give me
all the requested information, but we need that for analysis.
