When 0.0 and -0.0 occur in the same compilation unit (e.g. function), the first one to occur gets used in lieu of all occurrences of the other. So, I've added a unittest to confirm this bug, and slightly tweaked an optimization performed in ast.c (_exactly_ along the lines of the similar tweak that's already there in the similar optimization performed in peephole.c) to remove the bug (which was not in the latest released 2.4 but keeps resurfacing -- hopefully no longer, w/the new unittest). |

I'm still doubtful whether this deserves fixing. However, if it does, it should produce different literals for +0j and -0j as well. |

This can be closed, I think: it's already been fixed in the trunk (with a different fix, also due to Alex, from the one given here) and the fix has been backported to 2.5.2. Not sure what the appropriate resolution is here; plumping for 'out of date'. |
