The following code works with the FSF compiler but not with the recent

                  createEnd];
When built with the Apple compiler the code never returns from
setQuotedObject and CreateEnd is never called.  Execution sort of drops
through.  It may be important that this code is in the getExpr method
which is being called recursively to parse a Lisp data file.

Ok, one thought - the method setQuotedObject is probably something like

- (void)setQuotedObject:(id)anObject

or isn't it? Then the result of the above concatenation would be highly architecture dependent I think. It probably works on ix86 because the arguments are passed on the stack and not in registers, but that's rather a guess.
