First step is to take XWin out of the picture.  If this is a generic
problem with getmntent, then a standard getmntent loop should show the
same behaviour:

  #include 
  #include 

  int main ()
  {
FILE *fp;
struct mntent *mnt;

fp = setmntent ("/etc/mtab", "r");
while ((mnt = getmntent (fp)) != NULL)
  printf ("name: <%s> mount point: <%s> type: %s flags: <%s>\n",
  mnt->mnt_fsname, mnt->mnt_dir, mnt->mnt_type, mnt->mnt_opts);
endmntent (fp);
return 0;
  }

Now the question is, if the same problem occurs, why?  Please paste
the contents of /etc/fstab and, if it exists, /etc/fstab.d/$USER
into your reply.

Yes, please.

Assuming for the moment this is a defect in the cygwin DLL, it would be 
interesting to see the output of 'mount'.  You might also want to 
install the cygwin-debuginfo package and see if you can debug the 
problem in getmntent().


It might be worthwhile installing the latest cygwin snapshot [1] to see 
if the problem still exists.
