Got a compiler stack trace

Hello David,

Many, many thanks for the investigations! 🚀 Much appreciated.

It would be ideal if we can have a minimized test case (self-contained test file without dependencies to other libraries, or code, no zip-attachments) that demonstrates the compiler issue succinctly and possibly fits in the email body (if possible, of course; usually it is possible for compiler bugs).

For example, in your previous email "Found a bug?", even if you didn't include a minimized test file, pasting your code helped to reconstruct the issue, as the code was not attached.

Can you give it a shot with this one and provide a minimized example in your next email? 🙏

Please let me know if any more information is needed. I can also post this to the bug database like the directions say, just let me know.

Finally, I have attached another email thread that may be relevant. I don't think it is the same bug, but adding in case it is.

Thank you for your time and efforts!
