Subject: lseek 2GB wrap problem (with tail)?

Hello!

I've seen the following problem and don't know how to handle it.

Configuration: Cygwin 1.5.11-1, tail (textutils) 2.0.21, strace (cygwin) 
1.21

I noticed that various utilities (including grep and tail) have problems 
with the following textfile (let's call it test.txt):

"ls -l test.txt" gives  44589740378 (i.e. about 44 GB)
"tail test.txt" outputs some lines taken somewhere in the text file, but 
not the last lines of the file.
"strace tail test.txt" reports "lseek64: 1640067418=lseek(3,0,2)"

which obviously is filesize(test.txt) mod 2GB and which definitely does 
not point at the end of the input file.

I dont't know where to search the error, could anybody give me a hint?

Alexander Geraldy
