Hi,

i am running numpy on aix compiling with xlc.  Revision 1.0rc2 works
fine and passes all tests.  But 1.0rc3 and more recent give the
following on import:

Warning: invalid value encountered in multiply
Warning: invalid value encountered in multiply
Warning: invalid value encountered in multiply
Warning: invalid value encountered in add
Warning: invalid value encountered in not_equal
Warning: invalid value encountered in absolute
Warning: invalid value encountered in less
Warning: invalid value encountered in multiply
Warning: invalid value encountered in multiply
Warning: invalid value encountered in equal
Warning: invalid value encountered in multiply
Warning: invalid value encountered in multiply
Warning: invalid value encountered in multiply
Warning: invalid value encountered in add
Warning: invalid value encountered in not_equal
Warning: invalid value encountered in absolute
Warning: invalid value encountered in less
Warning: invalid value encountered in multiply
Warning: invalid value encountered in multiply
Warning: invalid value encountered in equal
Warning: invalid value encountered in multiply
Warning: invalid value encountered in multiply
Warning: invalid value encountered in multiply
[lots more of this]

The odd thing is that all tests pass.  I have looked, but can't find
where this Warning is coming from  in the code.  Any thoughts on where
this is coming from?  What can I do to help debug this?  I am not sure
what revision introduced this issue.

Thanks

Brian
