 The extractor for complex<> does not appear to
 construct a sentry object.  The sentry is where the 
 tying of streams takes action.
 For example, in the extractor for a double as found in
 include/bits/istream.tcc, the first statement
 constructs a sentry.
 
 Maybe the fix is a simple as adding that same line to
 the beginning of the extractor for complex<> in
 src/complex_io.cc.

 Dunno about that, though it's a nice thought.

 Re: libstdc++/943
 
 I am afraid, I cannot confirm. The problem still exists as of
 5/25/2001. Either this a problem with the flushing of cout, or the
 code is incorrect. But this code is extracted from the file num/complex2.cpp
 from the book "The C++ Standard Library" by Josuttis. Any clues?
