I did, and nothing happened for about 100 iterations. I have a Core
i7-2600. OS is otherwise identical to Manuel (Arch Linux).

I've seen it happening, but it is very rare. Still, the coincidence of
crashes during compilation could be explained by random chance (even if
very unlikely). A quick look over Scala's issue tracker reveals no
documented JVM segfaults after 2011.
