>Description:
I was overloading streambuf's in custom made streams, and 
noticed that it stopped working as expected in GCC 3.0. I 
cut it down to the smallest example which doesn't work, but
couldn't find where exactly is bad bit set - having trouble
drilling through with gdb 5.0.

I will try to look further into it, but here's an example program.
The second line never gets output. Maybe I'm using streambuf 
wrong, but the example works fine on windoze and gcc 2.96

Thanks,

Roman
