libstdc++/10809: [3.3 regression] mips-sgi-irix6.5 libstdc++-v3 testsuite execution failure in 27_io/istream_unformatted.cc

It's getting weirder: the log file contains

Assertion failed: i != 0, file 
/opt/build/eric/gcc-3_3-branch/src/libstdc++-v3/t
estsuite/27_io/istream_unformatted.cc, line 606

Now if I manually compile and run the test as you suggested, I get:

Assertion failed: sum != 0, file istream_unformatted.cc, line 619

and

i = 4294967295 
extracted = 0

I get random bus errors with both GDB 5.2.1 and GDB 5.3. And I can't 
step into in_avail (GDB jumps to the next line instead, after a little 
delay), not too sure why.
