Hi Eric
B is 71.8 Mbytes and and according to ls A (actually data.dat) is:
-rw-r--r-- 1 trader None 4540030014 May 26 12:00 data.dat
I'm running the latest version of cygwin. I hope you are able to reproduce
the problem with dd using this information.
Cheers
Peter

If that happened, it is a different bug, since dd does not go through the
stdio library, therefore does not see the bug in stdout being in 32-bit
mode instead of 64-bit mode. Exactly how big are a and b? I'd like to
try to reproduce this, and observe what strace has to say about it,
because I agree with Brian that it should work.

1.70.0? Not for many, many more years (after all, the 1.5.x series lasted
for several years). :) 1.7.0, on the other hand, might be released this
year, once it is ready. But in classic open source mindset, the release
will be sooner if you help.
