It's me again,
here is my 2nd problem:
I've got an ArbitraryPrecisionFloatTest failing with latest VMMaker.oscog changes (testErf).
This test was green previously - for example when I recompile VM source from SVN head revision - eliot 3651 which is also VMMaker.oscog-eem.1740
So it's most probably related to my recent refactorings on LargeIntegers.
Of course, Number tests pass, so I don't have a real unit test failing, more a kind of integration test because ArbitraryPrecisionFloat is shaking the integer arithmetic really hard.
The same changes are already on interpreter vm since july 2014...
So that's another flavour to test.
