Hi Rcpp-users: I am a very happy user of Rcpp. I am a statistician who can code a bit. Recently, I have been working on making my cross validation code run faster using Rcpp.
I have a question and wanted to check if others have faced similar problems. My code sometimes fails with a segmentation fault error, however this behavior cannot be replicated. That is, most of the times it runs fine and gives appropriate results, but once in a while it will fail due to segmentation fault and gives error like -- *** caught segfault *** address 0x18, cause 'memory not mapped' I don't think this is normal, but how can it give correct answers when it runs correctly. Any ideas? I would be happy to share code, but I wanted to see if I am missing something here. (I have limited experience as a C++ programmer.) Thanks in advance for your help. Best Regards, S.
