Bob -

I can no longer duplicate the original intent of this ticket, as the 
sample segfaults - when I try to cleanup the sample to avoid the 
segfault, I don't get any line number errors.

If you can duplicate the original line # error, please open a new trac 
ticket at https://trac.parrot.org/

I've opened the segfault as https://trac.parrot.org/parrot/ticket/1027 
and added a TODO test to track it in t/compilers/imcc/syn/regressions.t
