Basically you haven't deference thed pointers. You think you

in int's, the address of col, which is a large number since
user-land memory address starts at a large

Rather than trying to reinvent the wheel, why not make use of the
functions documented in Writing R Extensions, especially Calloc/Free?
And definitely do not call exit() from code linked into R: it is
antisocial behaviour to terminate your host's process.
Your example is incomplete, and for s
Hi all,
