Found a bug?

[David Alayachew]

Hello Amber Dev Team,

I was working on a project when, upon compilation, an exception occurred in
the compiler. Here is the error message.

Thank you.

I have also attached a zip file containing the project and the generated
output from this error. If this is indeed a bug, I will submit a bug for it
like the error requested. But I wanted to check here first.

Thank you for your time and help!
