One bug in the iostream part of libg++ I posted already for 
libg++ 2.2 is still there in version 2.3:

Using a iostream (or a derived) class for bidirectional I/O 
doesn't work properly because the flag _S_CURRENTLY_PUTTING isn't 
properly reset during a filebuf read after a write operation.

Here's the fix: (File libg++-2.3/libg++/iostream/filebuf.C)

*** filebuf.C-ORIG	Mon Nov 23 23:07:11 1992
--- filebuf.C	Mon Dec 14 13:05:09 1992
***************
*** 255,260 ****
--- 255,262 ----
  	if (do_flush()) return EOF;
  #endif
  
+     switch_to_get_mode();
+ 
      _G_ssize_t count = sys_read(base(), ebuf() - base());
      if (count <= 0) {
  	if (count == 0)
