Yes! I haven't really seen the 64bit problem myself, but you theory
sounds very convincing. This is very likely the solution.
What about this this patch, tho, which is exactly the same as yours,
but a bit more similar to the code we have:
137c137
< #define CELL_P(x) (SCM_ITAG3 (x) == scm_tc3_cons)
---
> #define CELL_P(x) ((SCM_UNPACK(x) & (sizeof(scm_t_cell)-1)) == scm_tc3_cons)
I'll put it in right away, with a comment.
Thanks a 18446744073709551616!
