Thing is, it worked in 1.23 (not 1.24) flawlessly both on interix and linux, so 
i don't think it's "only" a bug in the filesystem (although i'm with you: NTFS 
is a buggy fs ;)). also the strange time-related component while debugging is 
not explained by this. i suspect that a change in gnulib is the actual problem, 
but i was completely unable to find a hint.

I use NTFS on interix, and i don't know what darkside uses on linux, where the 
patch fixed the issue too (see the bug, i asked him about the filesystem).

Any other idea, apart from "filesystems fault"? I'll happily try to debug 
things, however for some reason the "bootstrap" script from git does not run 
when i checkout tag 1.23, but only with tag 1.25 ... i plan to try and bisect 
gnulib in the 1.25 tar build to get a better idea of whether there is a problem 
in there.
