An input file mock up script is as follows (tested/works):

This script only produces 9 columns of data. Running the
problem script against this mocked up data didn't cause any
exceptions.

I modified the script as follows to allow easier adjustment of
the number of columns in the mock up input data:

#!/bin/bash

mkdir final
mkdir sunshine

export COLUMNS=16

for FNUM in `seq 1 26`;do
        OFILE=`echo $FNUM| awk '{print "./final/test_file_" $1 ".final.txt"}'`;
        
	LINE=`echo $COLUMNS|awk 
'{for(i=1;i<=$1;i++){printf("HEADER_%d",i);if(i<$1){printf("|");}} 
printf("\n");}'`;
        echo "$LINE" > $OFILE;

        for L in `seq 1 992`; do
		LINE=`echo $COLUMNS|awk 
'{for(i=1;i<=$1;i++){printf("%d000",i);if(i<$1){printf("|");}} 
printf("\n");}'`;
                echo "$LINE" >> $OFILE;
        done
        unix2dos $OFILE;
done
#END OF SCRIPT

Using 9 columns didn't cause an exception or segfault.
I increased the number of columns to 16 and ran the other
problematic script again and again no exception or segfault.
(??) I am wondering if the Windows XP system is actually
violating the stack and not cygwin.
