[MacPerl] System Crashes when I run this Small Program... why?

[Alex Satrapa <packrat@blitzen.canberra.edu.au>]

I wonder if anyone can help... I've been trying to test a little routine
under MacPerl. When I run it straight through it works fine. However, when
I debug it, it hangs my Mac after executing the 'print "Boo!";' line.

Each execution of the File_Year routine works fine. If I put "exit" after
the fourth File_Year, the debugger will crash the Mac after executing the
"exit".

There's got to be some silly thing I've overlooked... can anybody show me
what I've done wrong?
