 A memo: while working on a fix for libstdc++/9423 (quite easy by itself),
 finally seems obvious how to fix 9024: in _M_underflow_common add a
 separate case for !__testget && !__testinit, which simply calls
 _M_file.xsgetn(&__c, 1) and returns __ret = traits_type::to_int_type(__c).
 
 Stay tuned!
 
 Paolo.
