funny strstream bug (yes I know it's deprecated)

People probably don't care about strstream any more but I still
thought this was an interesting one.
Self contained bug example follows:
---------------------------------------
#include <string>
#include <strstream>
int main(){
std::string fred = "
some_spaces_precede_a_single_exceedingly_long_word 1 ";
istrstream arguments((fred+" ").c_str());
std::string base;
arguments >> base;
int L;
arguments >> L;
cerr << "L " << L << '\n';
}
// Expected output: L 1
// Actual output on my system: L 0 (??!!)
----------------------------------------
Puzzlingly, the code can be made to work by replacing the words
'exceedingly long' by 'short' in std::string fred.
I'm running today's download of Cygwin and gcc on Win2000.
Any enlightenment welcome.
Yours
Brian Bull
