[R] memory allocation problem under linux

[antonio.dinarzo@studio.unibo.it]

I've written:

>  #define NMAX 256
>  long **box;
>  ...
>  box   = (long **)R_alloc(NMAX,   sizeof(long *));
>gives a null pointer, so subsequent line:
>  for (i=0; i<NMAX; i++) box[i] = (long *) R_alloc(NMAX, sizeof(long));
>gives a SIGSEGV signal.

Sorry, that's not exact: I have a segmentation fault just *inside* R_alloc!
Substituting R_alloc with malloc and Calloc gives the same error.
