  YES!
  You need to update lightning also, because I just found a bug:
http://git.savannah.gnu.org/cgit/lightning.git/commit/?id=ddd7a7550bb3be79b877d62c3028abe6462da976
then, with this commit:
https://github.com/pcpa/smalltalk/commit/9c3b8e57fd388a8202572b963c611bf518b183c0
it works in x86_64 also. Well, almost, but fails the same way as the
lightning 1 build
in make check, where it hangs in test 117.


  Off topic, kind of,

  I will make a battery of tests in lightning now, to attempt to find
other cases
where it could not be releasing a temporary. Enough to test is adding

assert(_jitc->reglive == 0);

after the "jit_regarg_clr(node, value);" call to clear that information, and
any other such problems will be triggered by the current test cases.

Thanks,
Paulo
