A simple case to make parser overflow stack

When compiling the attached file the parser overflows the stack. Then the code
to catch crashes and print out a stack trace is called and another crash
occurs, presenting the user (on Windows 7) with the 'close program'/'debug
program' dialog.

For comparison, Microsoft's cl.exe gives the following output when compiling
the attached file:

tail.cpp(2) : fatal error C1026: parser stack overflow, program too complex
