v.1200 32 bit (Intel)] on win32. )





Seems it's a Windows only bug.  On a 2.4.3 linux,

libc-2.2.5 the final

statement produces 5L (and the file is only 5 bytes

long).  Same on

another 2.4.19 libc-2.2.5, and a 2.4.21 libc-2.3.1

Linux, all with a

recent Python 2.4a0 .  

reproduce on Windows.
