What Peter & Vladimir refers to are the causes of problems - adding "-Wall" to all of CFLAGS, CXXFLAGS, FFLAGS should spot some of them. I did know of one case of uninitialised variable causing a crash - doing "FILE *file; close(file);" crashes with gcc but not with sun workshop (sun workshop imp

I got the same error with 64-bit R 2.4.1 on FC6 x86_64, and 32-bit R 2.4.1 on the same machine is okay. There is definitely something wrong with your code. I would suggest fixing all the compier warnings - there are piles of them about uninitialized variables, and about doing comparison between si
