In order to try Zoltan's suggestion, I updated to HEAD (from webkit-gtk 1.3.3, which is not a very old release) and the problem evolved: backtrace changed, both happens with and without JIT, but it still only happens on the laptop and not the quad-core.
Another interesting point: I added 5GB swap on the laptop (from the 2GB of RAM) and jsc is now working properly. :-)
