I've attached it at the bottom, but AFAIK there was only a single ActivePerl
release for 5.8.4 (build 810), so the output should be identical.

As everything worked for me, it seems unlikely that there is any #define
that would explain the difference.
Things that are still different in Heiko's setup are the compiler version
(Visual Studio 2003 I think) and OS (Windows XP). I've been using VC6 and
MingW for
the compilers and Win2000 for the test VM (but probably not MinGW with 5.8.4
because build 810 doesn't support this without some tweaks).

If anything I would suspect that the compiler version might make a difference
(and or the Platform SDK, if installed). But I'm not keen on spending too
much time on testing a 7 year old compiler with a 6 year old version of
ActivePerl unless the problem can also be reproduced with a current version
of Perl.
Ok, I have one more idea: When you compile a module with VS2003, then that
module
links against MSVCR71.dll instead of MSVCRT.dll, so you end up with 2 CRT
libraries
inside a single process. This normally works fine as long as you don't mix
things
like memory allocation (call MSVCR71.free() on a pointer returned by
MSVCRT.malloc())
and file I/O (call MSVCR71.fputs() on a FILE* returned by MSVCRT.fopen()) etc.
All the macro redefinitions in the Perl headers are supposed to protect you from
these mixups, but there may be a bug somewhere.
I don't have a VM with VS2003, and I don't know if I have a license anywhere
anymore
anyways, so it is not easy for me to test.
Cheers,
