Hello. I'm still working on my OCaml-R binding and I get a segfault in the GetNewPage() function of memory.c. For the record, the OCaml-R binding seems to work fine with OCaml bytecode. The segfault here is the main issue I have with OCaml native code. OCaml-R can be found on the following links. Source code: http://yziquel.homelinux.org/gitweb/?p=ocaml-r.git;a=summary http:...

Is it already known that R does not free the memory that it allocates during start-up (~10MB) when it exits? If so, are there currently any plans to address this problem? I noticed that the 1.6.0 beta leaks slightly more memory (~300k) than the 1.5.1 stable version. I am working on a project that links with the R library, and there is a question about unloading and later re-loading the

Dear list-members, I have observed quite a strange problem with the date package. You will find below what I get on my machine (Ubuntu). I have been able to reproduce the error on Red Hat too. But it seems not to happen on Windows (and on some other Linux distros?). > require(date) Loading required package: date > sessionInfo() R version 2.15.2 (2012-10-26) Platform: x86_64-pc-linux-gnu
