I had a similar problem when trying to use gunzip from a cmd prompt
outside of a cygwin shell - I was getting illegal ntvdm CPU errors. The
fix is to replace the softlink with a hard link:
$ cd /bin
/bin
$ ls -l zcat*
lrwxrwxrwx 1 lukeb Users 19 Sep 21 16:29 zcat.exe ->
gzip.exe
/bin
$ rm zcat.exe
/bin
$ ln gzip.exe zcat.exe
/bin
$ ls -li zcat* gzip* gunzip*
1125899906888251 -rwxr-xr-x+ 3 lukeb Users 62976 Jul 23 2003
gunzip.exe
1125899906888251 -rwxr-xr-x+ 3 lukeb Users 62976 Jul 23 2003
gzip.exe
1125899906888251 -rwxr-xr-x+ 3 lukeb Users 62976 Jul 23 2003
zcat.exe
I would suggest doing the same with any other cygwin executable that is
a symbolic link that you intend to use "outside" cygwin.
