FWIW, got overflow for the first expression. Second expression is okay 
on my PC, 32 bits, architecture x86, Intel Pentium 4 processor with HT 
(Hyper-Threading) technology and Microsoft Windows XP SP2 (Service Pack 
2), Mathematica for Windows versions 6.0.1.

In[1]:= $Version

Out[1]= "6.0 for Microsoft Windows (32-bit) (June 19, 2007)"

During evaluation of In[1]:= General::ovfl: Overflow occurred in \
computation. >>

Out[2]= Overflow[]

Out[3]= 9.601123363461783992717910966`15.954589770191003*^646456886
