This change (calculating and storing the offset in 
scm_make_continuation) makes sense, but I'd like also to understand 
where the bug was in my version (using offset = (SCM_CONTREGS (stack) -> 
stack) - SCM_BASE (stack);) and why my code worked in 1.6 but not in 
head.  Would you mind explaining?

Thanks,
	Neil

PS. Merry Christmas!
