Pete,
  I have the Modula-2 compiler, which may be what you
are referring to.  I have had problems passing variable
length string variables as parameters.  The string gets
corrupted somewhere on the stack, with funny characters
appended to the end.  Changing allocated stack size 
changes the appended funny character.  I was not doing
recursive calls.  I worked around the problem by declaring
the variable-length character string vars as global to
both caller and called, rather than declaring locally and
passing as parameter.
Don't know if this will help your recursion problem, though.
