I tried to minimize the code, but it seems to have disappeared..? I have reverted back the code I committed when I got the error and it no longer panics. I don't know much about compilers, but maybe y'all can read the stack trace and find something useful, though.
It looks like there are similar reports, but this one is from a different file, so I hope I'm not duplicating reports.
