I see this in every version of MinGW GDB since 7.8.1 (didn't try
earlier versions) when debugging a C program: if I step outside the
'main' function, i.e. past its closing brace after the 'return'
statement, I get an internal GDB error.
Here is the session with a simple "hello, world" program:

Is it a known problem?
