I am unable to get gawk to work with the following command line:

diff binarydata/400bongsrdsr binarydata/hfbongsrtest | awk -f differ.fil
| xargs error.exe

differ.fil contains the following line:

{ if ( NF > 0 ) { print "binarydata/dolbytonesrdsr " $3 " " $5 } else {
print "nul" } }

error.exe is a gcc (cygnus) compiled executable.  The two files being
diffed are just binary data files.  My problem arises in the else {
print "nul" } branch of the differ.fil file command line.  Cygnus
returns the following error message:

(C:\working\dsr\testfiles\error.exe 1034) Exception:
STATUS_ACCESS_VIOLATION
(C:\working\dsr\testfiles\error.exe 1034) Dumping stack trace to
error.exe.core

The contents of error.exe.core are:

I have not looked at this bug, but it seems to be fairly significant.

Thanks.
