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. -- Eric Botcazou
