valgrind and C++
I think the server that runs the valgrind checks is still running the old version of your package (2.17) not the new one (2.18). Wait for an update. Martyn

Hi, I am sorry if this is perceived as a C++ question rather than an R question. After uploading an R library to CRAN (MCMCglmm) the C++ code failed to pass the memory checks. The errors come in pairs like: Mismatched free() / delete / delete [] at 0x4A077E6: free (vg_replace_malloc.c:446) by 0x144FA28E: MCMCglmm (MCMCglmm.cc:2184) Address 0x129850c0 is 0 bytes inside a block of size 4 alloc'd at 0x4A07CE4: operator new[](unsigned long) (vg_replace_malloc.c:363) by 0x144F12B7: MCMCglmm (MCMCglmm.cc:99) which is associated with lines allocating and freeing memory (nG is an integer): int *keep = new int [nG]; and delete [] keep; To me this looks fine, and on my machine (Scientific Linux 6.4) using gcc 4.4.7-3 and valgrind 1:3.8.1-3.2 I get no such errors. Its not clear to me which flavour of Linux or compiler the CRAN team used, although from MCMCglmm-Ex.Rout I can see the same version of valgrind was used. Any insight would be very welcome. Kind Regards, Jarrod
