[Rd] segfault interest?

in a long program, I ran into

 *** caught segfault ***
address 0xdc3f9b48, cause 'memory not mapped'
 1: rep.int(seq_len(nx), rep.int(rep.fac, nx))
 2: rep.int(rep.int(seq_len(nx), rep.int(rep.fac, nx)), orep)
 3: expand.grid(seq_len(nx), seq_len(ny))
 4: merge.data.frame(d, ss)
 5: merge(d, ss)
 6: valid.range(opt)
 7: eval.with.vis(expr, envir, enclos)
 8: eval.with.vis(ei, envir)
 9: source("fut-into-opts.R")
Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

I am pretty sure that I can program around it (and it is probably
caused by my writing some error), but because it is replicable, I just
wanted to learn if anyone is interested.  oh---the program is pure R
code, nothing special (like linked in C code or stuff like this).  the
error occurs on OSX.  if there is interest, please email me and let me
know what would be most useful to supply.  if not, fine, too.
