I'm not quite sure that this is a bug, it's rather a difference in how
cfront handles strstreams and how (lib)g++ handles strstreams.
Here is an example:
////////////////////////////
#include <string.h>
#include <strstream.h>
#include <iostream.h>
char* str1="Now is the time for all good men ... 13:34:20 beep";
main()
{
istrstream istr1(str1, strlen(str1) + 1);
char buf[256];
while(istr1 >> buf) cout << buf << " "; // Don't forget to say "beep"
cout << endl;
istrstream istr2(str1, strlen(str1) + 1);
while(istr2.good()) { // Try again!
istr2 >> buf; // That's better!
cout << buf << " ";
}
cout << endl;
}
////////////////////////////
Compile with cfront and it prints the whole string twice.
Compile with (lib)g++ and it loses the "beep" the first time.
I can find good arguments for both behaviours.
Is it the program that is badly written?
Is there a definition of how it should work?
BTW, I last tried it with g++-2.3.3 and libg++-2.3.
Regards,
Johan
