Hohum, this is probably because I forgot to close() the file in the read() part of the test... *blush* I just reran the test on my laptop (arthur: Celeron (Coppermine) 500, 128MB, SuSE 7.0 + updates, linux-2.4.2, gcc-2.95.2) and got "only" 963 errors. I also ran the test om my desktop (zaphod: AMD K6-3D/333, 160MB, Debian 2.2 + updates, linux-2.4.2-pre4+reiserfs patch, gcc-2.95.2) and got 888 errors. An interesting observation is that the two systems have the bugs in almost the same places. Attached is a diff between the output files of both systems. Erik -- J.A.K.
