It may or may not be relevant, but there is a catastrophic bug in  
log10() in 10.5.2 for x86_64: it returns 0 for all arguments.  This  
has been discussed on the Scitech list.  Apple think they have fixed  
it, but I am sure they would want to hear of other cases or possible  
compiler issues, if it is their compiler you are using.

So if you can get a minimal test case it would be very good to submit  
a bug.  It may be worth doing even if you cannot get a minimal case  
because all the sources are readily available.

Finally last time I looked a few days back Simon's 64 bit Intel builds  
were failing.
