 hi,

 this is perhaps not a bug, but at least a different behavior between
 gcc 2.95 and gcc 3.0, and you perhaps can give me a hint for porting.


 the sample attached program makes 2 tests reading n bytes from
 a file ;
    test1 : file == std::cin     fails on gcc3,  succeeds on gcc2.95
    test2 : file is a std::ifstream, succeeds on both.

 Unfortunately I cannot attach you the input file since it's a 5769604
bytes confidential file, but **the same file** is used as input in **all**
cases.

 you will find as attached files

  1/ the bug diagnostic          bugrep00
  2/ the sample source file      test_istream.cc
