As the name suggests, it's an internal compiler error, that shouldn't
happen. The compiler's internal state became inconsistent. The internal
error is related to char to string type conversion.

Can you provide a code snipet that reproduces the error? Or at least the
code and the types involved at the line location where the error occurs?
