 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.
