Windows XP (SP3) , R 2.15.1 32bit Hi ... I have a script which fails and closes my R session. Unfortunately, it bombs out at a different point each time I run it. I'm guessing that it may be something to do with memory management, or perhaps it's to do with the various .C dll's the script calls.
Much more likely this one.
Has anyone come across similar problems and if so, how did you track down the cause ?
Valgrind perhaps? Or stepping through it interactively? See the Writing-R-Extensions manual for some tips, but it's a hard process. You'll likely be rewarded in spending at least a little time trying to identify which C call it is (first heuristic: if a crash is at line n, you can immediately eliminate all the C calls after n) Good luck, Michael
Pathetically grateful for any pointers ...
