in thread Exploring Inline::C (Generating primes)

Is it possible that your Inline::C is installed using a different compiler from the one used to compile Perl?

No, I've compiled 5.14 myself on this same machine, so the same compiler was used to build the whole setup. But that maybe indeed the problem : maybe I'm running the original system perl? I'll double check and retry.
