ftell() fails on files in shared folders

I have rewritten my program to use only low-level API (open, write,
lseek) and installed latest Cygwin. It seems that the error is caused
by O_RDWR - as soon as I change it to O_WRONLY everything starts to
work:

Local, O_WRONLY:
  C:\Users\gribov.y>\\s-cw-head\pgas\a.exe //s-cw-head/c$/test.bin
  success

Local, O_RDWR:
  C:\Users\gribov.y>\\s-cw-head\pgas\a.exe //s-cw-head/c$/test.bin rw
  success

Remote, O_WRONLY:
  C:\Users\gribov.y>\\s-cw-head\pgas\a.exe //s-cw-node01/c$/test.bin
  success

Remote, O_RDWR:
  C:\Users\gribov.y>\\s-cw-head\pgas\a.exe //s-cw-node01/c$/test.bin rw
  sizeof(data) == lseek(fd, 0, SEEK_END) failed at io.c:36
