Again, the only difference is 2.9.0 vs 2.10.1.  I.e., we used the same 
uulib library in 2.9.0 without these issues.  Unless do_ascii was modified 
between 2.9.0 and 2.10.1 to add uulib checks, this doesn't seem like it 
would be the source.  I will go and remove it however, since it is known 
problematic. :)
