I don't understand what you are talking about. Please upload a screenshot
where it shows the problem (if applicable).

i meant that all file sizes are 524288GB, take a look at the screenshot:

btw, i'm using reiserfs

There might have been some confusion between the off_t type and the output
in %llu format. I cleaned up the code so that no confusion should entail.
Please verify current CVS behaviour. (If problem persists, attach a copy
of your xffm/config.h file for further diagnostics).

i just (24.07) compiled xffm from CVS but the problem still persists

Could you please attach a copy of xffm/config.h to see what your computer
makes of the st_mode structure and other stuff?  Thanks.

sorry i couldn't upload it earlier - i was already in hurry posting last
message :)

The uploaded config file is practically identical to mine. Might be some
test is missing. What is the architecture on the box that exhibits the
trouble?

I compiled it like this: 
export CFLAGS="-O3 -ffast-math -pipe -malign-double -march=pentium2
-fomit-frame-pointer -fno-exceptions"

maby it's because this optimization?

that's possible.  from the gcc man page about -ffast-math:

This option should never be turned on by any -O option since it can
result in incorrect output for programs which depend on an exact
implementation of IEEE or ISO rules/specifications for math functions.

i don't know if xffm relies on this kind of stuff, but i really wish
gentoo people wouldn't bother reporting bugs until they ditch stupid
optimisations...  try it with '-O2 -march=i686 -pipe' and report back.

Ah, yes. The optimization flags are the culprit. I've compiled with the
same optimizations and get 16384GB for all files. This bug will be fixed
shortly. Thanks for the extra information.

AFAICT, the problem is with -malign-double. When you use it as a CFLAG, the
"struct stat" returned from stat() is borked. You might want to file a bug
with the gcc guys. The other flags you use do not seem to cause any harm,
at least on my box.
