Same problem on Sparc/Solaris 2.5.1 and 2.6, see PR libstdc++/10703.

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.

Thanks Eric.
Now, in order to make further progress, I have to ask you to debug a bit
that call (*): perhaps 'ioctl' returns zero (success) but __num is
unexpectedly zero too? Or is 'poll' to fail? Or, finally, 'fstat'
behaves unexpectedly?
Thanks in advance,
Paolo.
(*) Just copy the whole test file (together with the required
'istream_unformatted-1.tst') and replace <testsuite_hooks.h> by
<cassert> and each VERIFY by assert. Then build and step into that
in_avail call.

Hi guys. I'm suspecting this commit (of mine ;):
2003-05-01 Paolo Carlini <pcarlini@unitus.it>

Backport from mainline fix of 2003-03-28.
PR libstdc++/9533
I would appreciate if you could report on inadequacies
for your favorite platforms of the various system call
used in __basic_file<char>::showmanyc_helper
(in config/io/basic_file_stdio.cc). In particular: does
the autoconf test for 'fstat' succeed? If not, why?
Thanks for your collaboration, Paolo.

>Description:
I noticed that there is a testsuite regression on irix6 in 27_io/istream_unformatted.cc. See:
irix6.2: http://gcc.gnu.org/ml/gcc-testresults/2003-05/msg00943.html
irix6.5: http://gcc.gnu.org/ml/gcc-testresults/2003-05/msg00942.html
Looking back through the testresult archives, it looks like the regression appeared around two weeks ago in the May 2nd snapshot.
May 1: http://gcc.gnu.org/ml/gcc-testresults/2003-05/msg00066.html
May 2: http://gcc.gnu.org/ml/gcc-testresults/2003-05/msg00125.html
It's an execution failure. Running the binary I get:
Assertion failed: EX, file /caip/u58/ghazi/gcc-testing/branch/gcc-3.3/libstdc++-v3/testsuite/27_io/istream_unformatted.cc, line 606
Unfortunately I can't make sense of why it does this though.
>How-To-Repeat:
It's an execute failure, compile and run 27_io/istream_unformatted.cc. In my tree the command line to build it was the following, but it's very path dependent so you'll probably have to run the libstdc++-v3 testsuite on irix6 yourself:
