C# 9 Record: Compiler Created ToString() Code can Lead to Stack Overflow and Worse

When a record declaration has a property referencing itself, a reference cycle is generated which causes the compiler to write a ToString() method which will cause a stack overflow. The C# language designers say this is by design and refuse to issue a compiler warning, while most merely mortals would consider this a bug. Even worse, the debugging session might stop abruptly and the developer has no way to figure out the problem, because the stack trace is no longer available. Be warned when you design your own records.
